hey I had some other lines also that I'd like to ask if they are now obsolete or not

user_pref("browser.turbo.enabled", true);

Completely obsolete, does nothing.

"Pref removed (obsolete). Previously:

Determined whether to load browser in "Turbo Mode" (aka "quick launch") (Windows/Mozilla Suite only)

True: Load some Mozilla code into memory on Windows boot

False (default): Load browser normally on program execution"

user_pref("network.dns.disableIPv6", true); <--- increases speed when disabled?

Up to you, I've found it does increase page loading times a little, but it kind of messed up large file download speeds for me on some sites.

user_pref("network.enableIDN", false);

"Determines whether to use IDN (International Domain Name) support in the browser"

No reason to turn it off really. Was a security issue for about a week til they fixed it.

user_pref("browser.tabs.showSingleWindowModePrefs", true);

"Determines whether to display "Single Window Mode" settings in preferences.

True: Show "Force links that open in new windows to open in..." options under "Tools → Options → Advanced → Tabbed Browsing"

False (default): Opposite of above"

Pretty sure they're shown by default now in 1.5

user_pref("content.switch.threshold", 750000); <--- I have it at 750,000 instead of 200,000. What does that line do?

"Determines how long to wait for user input (mouse movement or typing) in microseconds until switching to low frequency interrupt mode. (High frequency interrupt mode provides better UI responsiveness at the expense of load time.) Default value is 750000."

user_pref("extensions.dss.enabled", 1); <--- This doesnt work at all. I dont remember where I got the info to put that line (which is dynamic skin switch)

"True: Enable dynamic skin (theme) switching.

False (default): Require a browser restart when switching themes.

Note: Switching themes dynamically is buggy"

user_pref("browser.sessionhistory.max_total_viewers", 5); <-- to load from cache?

"Determines the maximum number of content viewers to cache for "bfcache" (fast back/forward navigation). Default value is -1 (calculate based on available memory). All values less than 0 are equivalent.

Note: Firefox 1.5 and above only."

Explains each about:config setting

The Turbo one was for faster launching Firefox nothing to do with browsing, and it's obsolete.

The IPv6 setting Determines whether to perform IPv6 name lookups, so if it's disabled I'm sure it will give a slight performance improvement.

user_pref("network.enableIDN", false); Determines whether to use IDN (International Domain Name) support in the browser. So again you might see a slight improvement. And I think this was used as a security fix work around at one time. Meaning it plug a security hole...but that's since been fixed.

user_pref("browser.tabs.showSingleWindowModePrefs", true);Determines whether to display "Single Window Mode" settings in preferences. Nothing to do with speed at all.

user_pref("content.switch.threshold", 750000);Determines how long to wait for user input (mouse movement or typing) in microseconds until switching to low frequency interrupt mode. (High frequency interrupt mode provides better UI responsiveness at the expense of load time.) Default value is 750000. So the highter the threshold the better performance, I guess? This one is a little over my head.. but that's what it looks like.

user_pref("extensions.dss.enabled", 1); You are correct about that one, it's a dynamic skin switch, and they say it's buggy.. on that page.

user_pref("browser.sessionhistory.max_total_viewers", 5);Determines the maximum number of content viewers to cache for "bfcache" (fast back/forward navigation). Default value is -1 (calculate based on available memory). All values less than 0 are equivalent.

Note: Firefox 1.5 and above only. Supersedes browser.sessionhistory.max_viewers. This has to do with the fast back/forward feature as mentioned above..and btw has been said to cause high memory usage. This is what the developer was trying to explain and everyone jumped on the saying.. "high memory usage in Firefox is a feature" big joke to some anti-Firefox folks.

Most of these will give you very little speed boost, if any. IMHO

    • Quantum Error Correction Validated in Nature: Microsoft and Quantinuum Log 800-Fold Improvement Two years after the original press-release announcement, independently peer-reviewed results published in Nature on June 10, 2026, have confirmed that Microsoft and Quantinuum achieved an 800-fold reduction in quantum error rates on real trapped-ion hardware — the largest gap between physical and logical error rates ever independently validated.    What Quantum Error Correction Actually Does — and Why Breaking Even Is Hard https://www.techtimes.com/articles/318329/20260613/quantum-error-correction-validated-nature-microsoft-quantinuum-log-800-fold-improvement.htm   Quantum Computing Wiring Bottleneck Cracked by HKU Silicon Carbide Chip at Qubit Temperature Engineers at the University of Hong Kong have built the first cryogenic control chip that operates at the same temperature as superconducting qubits — 10 millikelvin, or just one-hundredth of a degree above absolute zero — without generating the heat that has forced every competing approach to park its electronics hundreds of meters of cable away. https://www.techtimes.com/articles/318325/20260613/quantum-computing-wiring-bottleneck-cracked-hku-silicon-carbide-chip-qubit-temperature.htm  
    • RevPDF 4.5.0 by Razvan Serea RevPDF is a free, fully offline PDF editor for Windows, macOS, and Linux that lets you edit text and images directly inside PDF files — no internet connection, no account, and no cloud uploads required. Unlike bloated alternatives that demand subscriptions and constant connectivity, RevPDF fits in under 60MB on desktop while delivering a complete editing toolkit: annotate, redact, sign, compress, split, merge, convert, and reorganize pages, all processed locally on your device. Smart font matching ensures edited text blends seamlessly with the original, and multi-language support includes RTL scripts such as Arabic and Hebrew. Where most PDF editors force you to choose between features and simplicity, RevPDF manages both. You can build interactive forms from scratch with text fields, checkboxes, and dropdowns, permanently redact sensitive data before sharing, draw freehand on contracts and diagrams, and add custom watermarks — all without a single file leaving your machine. Edit Text and Images Directly Inside PDFs RevPDF supports true inline PDF editing — not just annotation layers on top of a document, but actual modification of existing text and images within the file. A smart font-matching engine identifies the font used in the original document and applies it automatically when you make edits, so changes blend naturally with the surrounding content. You can reposition elements, resize images, and update text across single pages or entire documents. RevPDF 4.5.0 release notes: This is one of the biggest updates to RevPDF yet. A lot of things people have been asking for are finally here. New Features Auto Redaction Permanently redact sensitive text and areas from your PDFs before sharing. Clean, irreversible, and fully offline. Comments, Links & Bookmarks Add comments for review, insert clickable links, and create bookmarks to jump around long documents without scrolling forever. Find & Replace Search across the whole document and replace text in one go. Long overdue. Split Pages Vertically or Horizontally Split any page down the middle, vertically or horizontally. Perfect for scanned books or double-page spreads. New Drawing Tools More tools for freehand drawing and markup, better for annotations, sketches, and detailed notes. Continuous Scrolling in Editor The editor now scrolls continuously through pages instead of jumping between them. Working through long documents is a lot smoother now. PDF Metadata Editor View and edit the metadata stored inside your PDFs, including title, author, subject, and keywords. Better Font Matching Text edits now blend in more naturally by doing a better job of matching the original font. Tabbed PDF Viewer Open multiple PDFs at once in tabs and switch between them without going back to the home screen. Add Links Insert hyperlinks anywhere in your PDF, to external URLs or to other pages within the document. Share & Print Shortcuts Share or print directly from the editing screen, home screen, and viewer. No extra steps. Minor Updates Paste images directly from clipboard into your PDF New image editing tools for more control over images inside documents Bug Fixes Fixed file saving issues on Windows and Linux Everything still works fully offline. No login, no cloud, no account. Your files stay on your device.

    • Interesting. I'm not using a VPN with my phone. I tried though my home internet (Rogers) and my cellular internet (Telus) using their respective DNS servers and both trigger the dialog above.
