Neither the [`

So how do I get them running? A significant portion of the internet runs on WebM and the fact that Mozilla's own dev docs can't show examples is a good indication of a problem.

For some reason all of my bookmarks are gone. I have tried all the suggested fixes and it's still not working. Don't know where they went but I would sure like to have them back. Plus, now when I try to bookmark a page its not accepting it. :(

As per the title...

If I access "mail.yahoo.com" (specifically the site in the screenshot) at all in a Firefox session, that session is no longer able to play videos, i.e. Youtube, Tiktok, or any other streaming videos.

The videos "break" in that the player loads, but the content does not load, and the player is stuck endlessly with the loading circle animation.

Video previews also don't play when mousing over the thumbnails.

This is solved only by restarting Firefox, i.e. in a totally new session. It cannot be circumvented by opening a Private Browsing session, or new window, or closing the Yahoo Mail tab.

This bug is reproducible in a new profile: i.e. I went to about:profiles, loaded a new profile and opened browser in that new profile, went to mail.yahoo.com in one tab, opened youtube.com in another tab, and none of the videos (or ads) played in that youtube tab.

This bug is reproducible in troubleshoot mode.

This bug does not occur in a different browser, e.g. Brave.

This bug only seems to have happened recently, possibly with one of the recent updates. Edit: I rolled back to 143.0.4 and it still occurs.

OS: Win10 Home 22H2 19045.6456

I pressed "Share Data" for the troubleshooting information but it's not appearing in the question... not sure if I should paste that wall of text...

I have no idea how my bookmarks disappeared, but I cannot locate any of them. How can I get, at least, my bookmarks from one month ago. Have an upgraded computer, new hard drives, etc. I've searched my computer, cannot find any bookmarks. Is there hope? Win `11

A bit over a month ago, I was away from home for several weeks. When I came back, a browser that worked perfectly before became near unusable with constant and random crashes. Sometimes they occur even with no user input. I have tried troubleshooting mode, I have removed all extensions, I have tried all the fixes I found on Google, I have reinstalled the browser, I have updated all the drivers, I have done MemTest86 which was passed with flying colours and I have even installed a firefox fork (waterfox) to try and fix this all to no avail. I have no clue where to go from here, as it feels very bizarre. All help is much appreciated.

I don't know why, but every time i open a pdf with the firefox pdf reader i get this kinda grainy view of the pdf. If i do the same with google is all good. I really don't know what to do, can you help me?

bold text Every other day all bookmarks and tabs disappear using Firefox the only way for them to reappear is to uninstall Firefox and then reinstall it

i want to try vertical tabs to be able to see the tabs i have easier, and to be able to delete the ones i dont need anymore. but vertical tabs for some reason are unreadable. as in, the text does not show up unless you click on the tab.

is this a glitch? is there a way to fix this in settings or change the background or text color? (i think im running windows 10, if that factors into things. id love to not upgrade to 11 if i do not have to.)

Hello I am having major problems with Firefox at the moment and have done for a while. I curently have four pages open but as you can see from the attached screen shot of my Task Manager, there are 14 Firefox processes. The usage is OTT on memory and everything else. Could you tell me why this is happening? Currently it is running in Troubleshooting mode but that is not doing anything to improve the problem. It has been known to shut my computer down, as it gets too hot. I run on Windows 10 and Bitdefender is my security. All help is gratefully received. Thanks Lisa

i created a second profile yesterday. after starting the pc today, firefox opened and was empty/clean looking into the about:profile it said that i have two profiles but both were empty/clean looking into appdate structure > profiles i found 5 profile folders i tried deleting the profiles.ini, it created a new one but with the same new profiles i restarted the pc and had again 2 new empty profiles i tried creating a new profile with an existing file path and now i have 8 profile folders restarting again didnt create new profiles then i tried the "clean firefox" function but all i have after the restart are the 3 empty profiles again

how can i open the old profiles, of which the folders still seem to be there?

I have been having a problem for weeks with Firefox where it keeps resetting my default search engine to Yahoo. I tried a lot of things, including looking through all my extensions for anything untoward and most recently refreshing Firefox. The problem remains active. I would really like to not have to keep resetting my search engine every day.

Post-refresh, I find that Firefox is opening new tabs from links on pages I visit. That one is a REAL pain to deal with. It seems to kick in more on commercial pages than other pages. How do I stop that one? I already appear to be clear of bad extensions and I already refreshed Firefox1

I recently noticed that my Microsoft account remains active after I sign out if I press the back button. All my personal and account information is still displayed, indicating that the account is still signed in. I even tried clearing all browsing data and history, but that didn't resolve the issue. This doesn't happen with my Gmail account, nor when I access my Microsoft account using Edge or Chrome.

I understand that closing the browser likely signs me out, but I have no way to confirm that unless I check for active devices in my account settings. Can you explain why this timeout issue occurs? It seems odd, especially since Mozilla prioritizes security and privacy.

Websites like Medicare.gov give message like "We can't process your request at this time." This happens with increasing frequency on pages I know are valid and secure. MS Edge opens them with no problem.

Another example - my bank web site. Firefox triggers a whole series of confirmation tests from them but Edge gets in with just ID and password.

I am using a VPN from Malwarebytes. Windows 11 is the OS. Latest version of Firefox is installed (144.0.2 (64-bit))

I have been a long time Firefox user, but am starting to drift away to Edge because it connects to more web sites with less hassle.

What are my options?

I don't have, and think I never had, an authenticator app. So how is the replacement MacBook requiring 2-step authentication that requires an authentication app before I can sync to my Win 10 websites? I am new to the MacBook, and it would help to know if it has an authenticator app, and how to get it to work with Firefox.
