3. extract from there the file install.rdf

4. edit it with notepad

Thank you captain obvious.

This has worked since day one.

Nightly Tester Tools is still the best option.

if you want to get technical, in day one there was only one version of Firefox..

you can go to about:config and create a new boolean key called extensions.checkCompatibility and set it to false but in the add on menu it will give you an ugly red message in every extension that says "not compatible with Firefox 2"

This is my preferred method. I like the visual that shows which extensions have not been updated by the developer. That way if there is an issue you can disable them first. No extra extension to install. No hacking the extensions to make it work. It's simple and gets the job done, but is easy to undo later should the need arise.

Or you can use MR Tech Local Install. Much easier. Plus it does the job of over 40 extensions in one.
I've seen this extension mentioned on several boards, but I'm a bit confused as to what it actually does. Is it like Nightly Tester Tools, or completely different?

    • App, useful & Teams shouldn't be used in the same sentence.
    • New Outlook for Windows and Web is getting a simple but very useful email feature by Sayan Sen Recently Microsoft put up a blog post highlighting not one, not two, but 15 total reasons why it feels you should switch to New Outlook already. If that was not enough, the company is bringing another new feature soon that could finally compel you to switch over to the new app. According to a recent update on the Microsoft 365 roadmap, the tech giant is making changes to how message sorting works when users choose criteria besides the traditional options of From, Subject, or Date Received. The idea is to provide better options for the attribute being used for sorting and make it easier to understand why messages appear in a particular order. For those unfamiliar Outlook already allows users to sort emails using a variety of fields including sender, category, importance, subject, and message size. Users can access these options through the Filter menu in Outlook for Windows and Outlook on the web. With the upcoming change, whenever users sort by a field other than From, Subject, or Date Received, Outlook will automatically display an additional column showing the value being used for the sort. For example, if messages are sorted by Size, a Size column will appear in the message list, allowing users to immediately see the data that determines the ordering of emails. Microsoft believes this should make sorting behavior simpler and reduce the need to manually adjust views or inspect individual messages. Support for sorting by Flag Due Date is also coming and should be especially be helpful for users who rely on email flags to manage follow-up tasks and deadlines. The feature is listed under Microsoft 365 Roadmap ID 564803 and is expected to reach general availability beginning later this month itself (June 2026). You can find the entry here. As always though, users should keep in mind that roadmap timelines can change and rollout schedules may occasionally be adjusted by Microsoft. Outlook for Web is also set to receive this feature.
    • That is true. but the liability side of my balance sheet is clean and has been for decades.  Nobody comes a knocking,  calling or writing harassing me for the money i owe them.😎👍  Haven't dealt with "a money changer" in decades and like Jesus it was in Jerusalem.  Don't have much money, but have even less stress in my life.👍👍     P.S.  Sorry, can't walk on water or change it to wine,  
    • Maybe ? DLSS Swapper (can swap the DLSS/FSR/XeSS versions) as long as the game (typically online/competitive) doesn't checks for file tampering. You can try different version(s) or update if not the current version of the FSR. https://github.com/beeradmoore/dlss-swapper
