I have three disabled extensions that came with another software. "Adobe Contribute Toolbar", "HP Smart Web Printing" and "Java Console". I didn't have the option not to install them at installation. And even if they are disabled and do nothing, is there a way to permanently delete them? I'm on Windows 7. I didn't find anything on the profile folder.

in about:config, set plugin.expose_full_path to true, then go to about:plugins

That should show you the paths that plugins are installed in.

Remember to put plugin.expose_full_path back to false after you're finished, otherwise you can expose details about your plugins' folders to websites or something.

Most extensions are installed under AppData, but these may be in Program Files\Mozilla Firefox\extensions. Don't just start deleting things as one of these folders contains the default theme. Under each folder, open install.rdf in Notepad and see which extension that folder is for.

Ok, "Java Console" is gone. Still couldn't find the other two. Which sub-folder in AppData? I looked all Mozilla folders, but they are not there. Do you mean the folder AppData?

AppData\Roaming\Mozilla. Extensions here should be uninstallable though.

Also search your registry for "MozillaPlugins". There's two folders on x64 systems, so if you're running 64-bit windows, be sure to check both.

So, I deleted the registry entry for the HP Smart Web Printing and it is still there. Extensions folder on AppData\Roaming\Mozilla is empty. I wonder if they are located somewhere else? Also, it is 64 bits!

Wrong extensions folder. They're located in:

AppData\Roaming\Mozilla\Firefox\Profiles\RANDOMCHARACTERS.default\extensions

If that doesn't help, just search your entire PC for *.xpi.

I did it. But with other ways. You see, Smart Printing was a software. I had to uninstall it. In the Adobe case, I had to go to the Contribute folder on Program Files (x86) and delete the "plugins" folder there. it didn't show on the about:plugins page.

Anyway, thanks for the help!

It can be "hidden" in ProgramData folder, on Your system partition. If You want get rid some unwanted extension from Your addon manager navigate to Your profile in %appdata% -> open profile-> locate config file called "extension" and delete from there directory to unwanted extension. But for every case make backup of this file before edit.

      This seems backwards. You should have to explicitly authorize files for outside use. It shouldn't be the default.

      Wow you are right, I never even noticed this until you said it! (870E Aorus Master) Before testing this card I had a TP-Link tx401 10GbE PCIe card in that slot (now using XikeStor 310 Thunderbolt to Ethernet adapter).

      Lack of 5.1 makes this a no sale. What I really wish creative would make would be a USB version that supports 5.1 analog audio for speakers, can switch to headphone mode, and matches the specs of their top tier cards. The current X870E AMD motherboards dont have a great option for adding a PCIE x1 card without cutting down pcie lanes to the graphics card.
    • The Microsoft Office feature that time forgot

      By Usama Jawad96 · Posted

      The Microsoft Office feature that time forgot by Usama Jawad I have been actively using Microsoft Word for the past couple of decades in academic, professional, and personal capacities. Although I used it through the perpetual version of Office apps at the start, I have been an active subscriber of Microsoft 365 Family subscription for over five years now. This means that my Word installation is regularly updated with new features, some of which I don't really like, but that's beside the point. As new features get continuously added, old ones that used to be a staple of Word have started to take a backseat. While I was reminiscing over my Windows experiences from my childhood today, I suddenly remember one such capability that I heavily used in my younger years but have not really touched in over a decade, and haven't seen in documents created by others either. That feature is WordArt. Just to clarify, WordArt is not a Microsoft product specific to Word, and is included in other Office apps like PowerPoint and Excel too. However, Microsoft Word is the app that I used Word Art in heavily, while making assignments or other deliverables for school. If you're unaware, WordArt offers a collection of styling techniques for text, introducing 3D effects like shadows and reflections in the text. It used to be one of the coolest things ever when I was at school and me and my classmates would often compete to ensure that our assignment's title in WordArt was truly the best and stood out above the rest. See some examples of WordArt, still present in the latest versions of Word below: Although WordArt is undeniably cool, it has taken a bit of a backseat, and has been relegated from the Home tab to the Insert toolbar, along with a bunch of other utilities, making it very easy to miss. This isn't exactly surprising because WordArt doesn't really have a place in academic and professional documents anymore, and while I have seen some creatives using it while developing promo material, even that sector has gravitated more towards dedicated graphic designing tools in the past years. For the vast majority of us, WordArt doesn't really exist, and that's alright. At least, it's still an option that can allow us to reminisce our childhood or even make some quick text stylization, if we really need it. Perhaps its usage has waned over time or the novelty has worn off, but I haven't even seen children use it in their academic assignments anymore. In fact, many don't even know that it exists. Maybe that's the fate of every beloved feature. What once felt cutting edge eventually becomes a relic, quietly tucked away as tastes, trends, and technology move on. WordArt may no longer dominate school assignments or decorate the covers of classroom projects, but for those of us who grew up with it, it remains a colorful reminder of a time when making text glow, bend, and cast giant shadows felt like the height of creativity. Hidden behind a few clicks in modern Word, it still survives not as a productivity tool, but as a small piece of computing nostalgia that refuses to disappear.
