Apparently Windows 11 won't upgrade from v23H2 to 24H2 because the very nice cpu (and system) don't support SSE4.2 or PopCnt instructions. While v23H2 won't get updates after November of 2025, I tend to use operating systems WAY beyond no more updates without problems, and only upgrade when browsers no longer update and support some websites, notably banking and credit card sites, for example.

Any way to get at least a rough idea of when/how long Firefox will continue to update on Windows 11 23H2 so I can plan ahead? Usually it's a year or 2 or more after Microsoft stops updating the OS.

Thanks.

I'm very frustrated with FF. It's running slow. Downloads are slow etc. I've tried everything that FF has recommended up to and including "refresh" with no effect. It's getting to the point I'm considering not using FF. Does anybody have any suggestions?

I often hit ^T (control-T) in firefox without meaning to, because I use that chord in other applications a lot. In firefox it opens a new tab, which is almost never what I want. I'd like to suppress that keyboard shortcut. I tried doing it using vimium (unmap <c-t>) but that has no effect.

Thank you, Silvio

Avast reports that it has secured the threat of 'addons.mysafe-search.net' which tries to start when i open Firefox. I've been unable to find any reference to the site anywhere on my PC so cannot uninstall it.

If I go on any website using OSM data (including OpenStreetMap itself) on Firefox logged into my account, I experience a lot of slowdown. This doesn't happen when I use incognito mode or when I use another browser, so I'm pretty sure there's some kind of cache or something that's connected to my Mozilla account that slows down OSM massively. I've tried clearing all cache and all cookies. I've even refreshed Firefox using the installer and it's still slow. I don't want to bother with deleting my account and creating a new one. What should I do to try and return back to normalcy on OSM?

bold textPasswords and Sign In

Hi,

I had some hardware problems on my old PC and for some reason most likely to do with accounts when I restarted on Win 11 on new PC I had lost the majority of passwords saved to the Browser Password manager.

I have lost my old email address and am having some issues working out whether for some reason on the old system I was using my old email address to log in.

Is there any workaround to trying to determine whether I have a seperate account possibly linked to old mobile or email account that may link to the Password manager that contains my old PC systems password link.

I am setting up a more secure way to save passwords also? Is it better to use a portable hard drive rather than something cloud based for passwords?

I am a senior and at times do make some elementary mistakes with digital literacy so sympathetic answers would be greatly appreciated.

Today Firefox crashed twice and a Tab crashed once! What's going on with Firefox? It's especially disurbing to have it crash during a long video and then you have to find where you left off.

Every time I start Firefox after closing it, I get a screen saying "Your Firefox has been updated" plus an announcement about editing PDFs in Firefox. My degault home screen does not appear unless I click the "home" icon. This is frustrating, because the update message just won't go away.

The URL for that irritating message is: https://www.mozilla.org/en-US/firefox/135.0/whatsnew/?oldversion=134.0.2&utm_medium=firefox-desktop&utm_source=update&utm_campaign=135

I've attached a screenshot to show this, hoping you can suggest a way to fix the issue.

I just installed the MozillaVPN extension on my Windows10 laptop but can't use it because when I select the tool, it tells me to download and install Mozilla VPN - which is already running ! I've tried closing and re-strarting Firefox, and stopping & starting the VPN manually, but that doesn't make any difference.

Every time I try to view a pdf file on Firefox I can view the file but in the lower right 1/4 of the screen I get a graphic of a page with shaded areas representing lines with writing on them. There is a type of pen cursor moving along the line.

This happens with different pdfs - from the internet and from my saved files. This doesn't happen on another computer with Firefox.

I've deleted and redownloaded Firefox an number of times, also tried troubleshoot mode - no improvement. Virus scanned, restarted a number of times.

Pdfs work on edge and chrome and reader with no problem.

I have a screenshot.

Any Ideas? Thanks

google search said this is Firefox intertnet speedtest app or extension but the actual descriptions says it's not monitored?? does firefox have a secure internet speedtest? why are these blank?? We've made some educated guesses about your current browser and operating system

is this support or forum??

Why can't I sync computer bookmarks to iPhone? I can't get my iPhone to show up on list of connected devices. I've tried everything in Help. I have a Mozilla Account. Running 135.0.1

From the Firefox Start Page on my iPhone (running 18.3.1) . . . the menu in the bottom right hand corner does not give me the option to "Sync and Save Data". This is a roadblock for me! I'm not a computer genius but I'm not completely ignorant. I should be able to do this! https://assets-prod.sumo.prod.webservices.mozgcp.net/media/uploads/images/2025-02-28-15-53-59-c3d764.png Help please!
