Hello. I am not familiar with this end to end encryption that Facebook now does for Messenger but now when I try to use Video Calling/Chat it tells me it is not supported by my browser, Firefox. I have never had any problems with it before. Is there a fix? Thanks

I have set Firefox to not automatically restore the previous session on launch. That is, "Open previous windows and tabs" is unchecked in the Startupsettings.

Most of the time it does not do so, however the previous session will get erroneously auto-restored in the folowing circumstances.

Open a few tabs in a normal Firefox window. Fully quit Firefox (via, for example, pressing ctrl+shift+Q). Open a private window first. Open a normal window second.

What should happen is that the new normal window contains just a single new tab. What actually happens is that the tabs that were open in the previous session get auto-restored in this normal window.

To sum up, there is no auto-session restore if Firefox is launched with a normal window first. There is auto-session restore if Firefox is launched with a private window first, and then a normal window is opened second.

Is this a known issue, and are there any known fixes to prevent the auto-session restore in the latter case also?

After uninstall and reinstall my Firefox i can't restore my bookmark. I used (CTRL+shift+b) and restore my file "JSONLZ4". But i have an error as "Unable to process the backup file". I read your forum and test many things but nothing. I also used the https://www.jeffersonscher.com/ffu/bookbackreader.html,but it does not work? It prompts:failed JSON parsing: SyntaxError: Unexpected end of JSON input. I really need my bookmarks! How can I restore them?

I'm really shocked that the developers at Firefox has not at all fixed the memory leak issue, which caused my PC to crash three times in a row. This is clearly unacceptable; even other browsers I use don't eat up a lot of RAM in a matter of seconds that ends up my PC lagging, or worse, crashing as a result. To the Firefox devs; why are you overlooking an ongoing issue that should've been easily fixed from the get-go, especially with updates that obviously have nothing to do with the memory leak issue? It's really easy to make such a popular browser not hog up memory so easily without causing so much lag, even on higher end PCs.

If the memory leak issue isn't fully resolved by greatly reducing memory usage, especially if I'm only using one or two tabs with me, I will have to consider seeking for another working browser that does not have a memory leak issue, and remove Firefox and never reinstall it altogether.

I am using a windows 10x64bit desktop and I want to find a 32 bit version of Firefox for my laptop which uses Windows 7 x32bit. I have tried the download for customising, ie set it for Win7/8 but the version which is downloaded reflects on the laptop that that version can only be used on a Win 10 computer. Please give me a link where I can find the 32 bit version of Firefox meant for Win 7. THANK YOU.

Hello,

My microphone has recently stopped working on Firefox, and Firefox only.

It works in Chrome, Edge, and Opera.

I have tried reinstalling Firefox (and testing the mic with a clean install), reinstalling all of my audio drivers, and even changing the frequency of my Windows sound to a lower one. Nothing has worked.

My laptop is a Lenovo Slim Pro 9i (if it matters) and my microphone is an Intel Smart Array.

I have completely run out of ideas, so anything will help at this point.

Firefox can’t establish a connection to the server at 164.100.251.16.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

I've been able to change some of the Tooltips in my Firefox, but there are still that I can't edit. I've not been successful on Thunderbird at all. Using this in my Firefox's `userCrome.css`:

` tooltip {

   padding:          .5rem 1rem !important;
   color:            var(--light0) !important;
   background-color: var(--dark0) !important;
   border-color:     var(--neutral-orange) !important;
 }

` The "Show your Bookmark", "Open a new Tab", "Back/Forward", "Reload", all of my bookmark websites work. The "Home", "Open application Menu" and "Extensions" still show a black bg w/white text. Switching to a light theme shows the white bg w/black text, so it's a theme issue and not a Operating System (Win 10) thing.

I can't seem to get any of my custom Tooltip colors to show up in Thunderbird.

Any help would be appreciated!

How do I stop these recurring update notices? Every 3 seconds. I'll update when I am ready as this current one does not affect me at all. For a while I fell for it, stopped what I was doing and did the ridiculous update, it still continues! I can move on to a different non-Mozilla browser if I have too. Return the option to not update and/or do it manually. FF127.0.2

In Gmail, I repeatedly get "oops the system encountered a problem (#001)." Every other site works and Gmail works in other browsers. I haven't had any new add-ons or made any changes to Firefox (other than Firefox updates) in years. Does anyone know the fix?

hello tried a few things from help docs on line. nothing working. just keeps happening. tabs will say gah. your tab just crashed. works for a bit but once happens.... have to close whole firefox and open again. just started happening yesterday. I have used firefox for many many years never a problem. Something was not updated right.

For a while now, I've been having recurring issues with Firefox desktop freezing and becoming totally unresponsive. If there's any pattern to what causes it, I haven't been able to notice it; sometimes it happens as soon as I open the browser, sometimes it happens after several hours, sometimes it happens twice in ten minutes, sometimes it happens twice in a few hours (however, I can count the number of days it's happened less than twice in one day in the past few weeks on the fingers of one hand). When the browser freezes, it becomes totally unresponsive - it doesn't fade or display "Not Responding", and Task Manager shows nothing abnormal, but it doesn't accept any input at all, any video or other animated material that may have been displaying freezes, and it can only be "fixed" by force quitting from the task manager and reopening. This is exclusively a firefox issue; other programs open at the same time as the browser freezes are not affected.

The only real lead I have as to what could be going on is that sometimes, things don't freeze all at once, but in a cascading effect. For example, tabs, bookmarks, etc. might not highlight when moused over, but still accept the clicks, or selecting another tab might causes the address bar to display the URL of the selected tab, but the screen displayed in the window will not change. Once these cascading changes start, they generally progress to total freeze before I have a chance to do much with that information (only a few seconds), but it's unusual enough behavior to be worth noticing.

Things I've already tried that haven't fixed the issue:

• Reducing the number of tabs used and otherwise reducing Firefox's system resource usage has not impacted the problem in any way.
• Running in Troubleshoot Mode has not had a consistent effect on the problem (the most recent time I did, the browser ran stably for longer than I could stand to use the internet without my ad blocker, but this is only one data point in an already inconsistent spread; prior instances of the problem have occurred in Troubleshoot Mode)
• Disabling hardware acceleration has not fixed the issue.
• The issue has persisted through multiple refreshes and at least one full uninstall and clean reinstall.
• The issue persisted after creating and switching to a new profile multiple times.
• The issue persisted after renaming places.sqlite
• The issue persisted after clearing cache and cookies multiple times.
• The issue persisted after clearing downloads and history.
• And very likely some other stuff that I'm forgetting, I've been trying to fix this on my own for a while now.

I want to install the older version of Mozilla firefox for windows 11 in Spanish and Dutch language, please provide the link for Spanish and Dutch for ex. 125 version of Mozilla Firefoz

I have been using [edited] @comcast.net as user name for Firefox account. I want to delete that email because I'm leaving comcast ASAP. I read instruction that say add a new email name as a secondary account and then delete the primary one above. I entered [edited[ @gmail.com. I got a message that said that account already exists. Since I didn't know that or remember any password for it, I entered [edited] @gmail.com and said "forgot password." I changed it Now Firefox won't let me in using the [edited] @gmail.com account. Would appreciate any help you can offer.

I have noticed in the past few weeks or so, many video play backs are erroring out on google/news: Example: https://6abc.com/post/middle-schoolers-create-20-fake-tiktok-accounts-impersonating/15039963/

Message is: Media could not be loaded, either because server or network failed or because format is not supported.

IMO not a network issue......

Thanks John Hutchins
