I-Firefox Community Forum

Firefox repeatedly crashes on my, multiple times a day. I'dc really like to NOT have to change my default browser to Chrome.

What happens is that Firefox freezes, and I get a white bar at the top telling me so. I get a popup box asking if I want to close Firefox or wait for it to respond. Waiting doesn't work, so I always have to close Firefox. When I reopen it, fortunately all m,y open tabs are retained, but it crashes again within minutes or seconds as soon as I click on anything.

There only thing that seems to work is a reboot of my PC. But the respite is short before Firefox crashes again.

I've disabled most plugins, but that hasn't helped. Is there a way to create an event log within Firefox that I can share with someone at Mozilla to help e debug the issue? It's got to be something local rather than Firefox itself; I can't imagine this is happening to most users.

It's apparently well known that Firefox and Gmail don't play nice together, apparently because of how Gmail uses Java. Is there a plan in the works to fix Firefox so Gmail isn't so absurdly slow? I don't *want* to switch to Chrome, but I don't want to stop using Gmail either.

I have a new Yoga Pro 7 and installed Ubuntu 24.04 on it. Cannot enable hw acceleration on it. Support page is given below. It says disabled by gfx. Also vainfo output is given below.

For the last few weeks I have been unable to save new bookmarks into the folder of my choice. Instead I can only save new bookmarks into the last folder I created. I cannot navigate to a different pre-existing folder. This problem only occurs when using Firefox on my Android cell phone, but not on my PC. However, I can still view and use all of my previous folders and bookmarks when wishing to open a new website, per usual. Thank you

I come to Mozilla Support and at the top It's telling me windows 10 expires 10/14/2025. I don't need to know that I have windows 11. No one from Firefox to answer me directly??

I was told from a vendor I previously purchased from the insecure connection was on my end. Also on my Hotmail Acc. I experienced the same thing.

Thanks, Bill

P.S. I'm not tech savvy

Firefox 144.0 on a W11 PC with all updates.

Firefox is running multiple (10-13) windows with 5-10 tabs each. Even if all Firefox windows are minimised and not being used, memory usage goes up all the time. It is currently, according to Task Manager, using over 5 GB of 32 GB of available memory. CPU is sitting at ~4%. Individual tabs, like Youtube watching CNN suddenly freeze and are no langer accessible and can't be unfrozen by anything I have tried. Even the mouse pointer is not displayed inside this tab I need to restart the entire PC several times a day only to have Firefox usable. I have turned off efficiency mode, but this did not change anything. I'll include a system snapshot with msinfo

Any ideas?

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

Firefox: 144.0.2 64bit

Extensions: Clickbait Remover for Youtube Google (verbatim) search NoGoogleAi Old Reddit Redirect Ublock origin Video DownloadHelper Youtube Anti-translate

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...

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.

So if you go to My documentation page , go down to point 8 and try and copy the Systemd unit file from the browser to an editor, the line returns are not preserved and instead spaces are substituted. If I copy the text from a chrome browser into an editor, the new lines are preserved. I've copied the HTML source code below.

       [Unit]
       Description=Apache Tomcat 11.0 Web Application Container
       After=network.target
       

       [Service]
       Type=forking
       

       Environment="JAVA_HOME=/usr/lib/jvm/java-1.25.0-openjdk-amd64"
       Environment="CATALINA_PID=/opt/tomcat/Base/temp/tomcat.pid"
       Environment="CATALINA_HOME=/opt/tomcat/tom11/"
       Environment="CATALINA_BASE=/opt/tomcat/Base/"
       Environment="CATALINA_OPTS=-Xms512M -Xmx1024M -server -XX:+UseParallelGC"
       Environment="JAVA_OPTS=-Djava.awt.headless=true -Djava.security.egd=file:/dev/./urandom"
       ExecStart=/opt/tomcat/tom11/bin/startup.sh
       ExecStop=/opt/tomcat/tom11/bin/shutdown.sh
       User=tommy
       Group=tommy
       UMask=0007
       RestartSec=10
       Restart=always
       [Install]
       WantedBy=multi-user.target
     

So the code is rendering correctly in the browser, but is being incorrectly copied by Firefox. Note if you copy the above from this forum across to an editor the new lines are preserved, but if you copy it from the website they are not.

I am a pensioner in te UK. Due to restricted mobility I spend a lot of time using Firefox to access many web sites. This normally works perfectly. Today I tried to access the web site of national chain store specialising in outdoor clothing and equipment because I need a new showerproof jacket. I have never used that site before, yet Firefox reported Error 403 : Forbidden. Have you people never been told tat error messages are supposed to be useful? What is Forbidden. Why when it has not happemed before?

The web site is https://www.millets.co.uk/

I have a web site so I have other browsers just for checking for layout problems.

I tried Chromium, same error but the message said You are not authorised to access this site. Presumably that is what your incompetent message should have said. But why should a pensioner trying to buy something from a chain store ever need any sort of authorisation?

I tried Opera. Connected me no problem!

I tried Edge. Connected me no problem.

Clearly somebody somewhere is an incompetent idiot, but it isn't me. So who is it? If it is yourselves then please do something to fix this.

I've been having this issue for several weeks now. I have an HP desktop PC, with Windows 11, and the latest update is:

2025-10 Cumulative Update for Windows 11, version 25H2 for x64-based Systems (KB5070773) (26200.6901) - which happen ed yesterday, and this problem has been going on for a week now.

When I click on Bookmarks -> Manage Bookmarks; all my Bookmark Folders/sub-folders are listed, however when you click on an individual folder/bookmark - the Bookmark Properties are totally blank at the bottom of the screen. The RED ARROWS point to the area where any bookmark listed all have the same missing Properties area.

Notice the icon to the left of any bookmark? It looks like a globe. All individual bookmarks have this same icon, where before they could have and did have different icons to the left.

The BOOKMARK NAME is displayed, but the URL ADDRESS is missing for each and every bookmark listed.

This makes this browser, which I've used and loved for many years, TOTALLY USELESS....!!! I have uninstalled Firefox, reinstalled, and the bookmarks are still missing their properties. I have to delete and import bookmarks to get this to work. BIG PROBLEM: When I leave my PC on overnight with nothing executing, the next day when I launch Firefox, what was there before and functioning, now all bookmarks are missing as described above. Nothing changed overnight and Firefox changed something by itself that I didn't initiated.

Please investigate, correct the code, and send out an update immediately. IF NOT FIXED ASAP, AFTER USING FIREFOX SINCE IT WAS FIRST INTRODUCED - I AM GOING TO DUMP THIS BROWSER FOREVER. ARON COOK

Please tell me how to disable adblocker for a site. I am trying to read my local newspaper and I cannot access it due to this issue. I've googled it and cannot find the answer. Please Help!!!

I'm running Firefox 144.0.2 (64-bit) on a Mac using Sequoia 15.4.1 OS.

At the most recent Firefox update, I added VPN.

Since then, I've had a problem with Firefox hanging. Not immediately but after varying amounts of time, 20-60 minutes. I get an "Out of Application Memory" pop-up but the usage for both Firefox and other elements are well within normal range, not high. It's completely frozen and the only way out is to do a Force Quit.

There are times when doing a shut down I notice that VPN has somehow been turned Off and once I saw a message of Background Service Error attached to it.

Having to constantly re-start Firefox is a major pain. Oh-- I did turn off the background AI thing under Tabs. I hate AI and try to turn it off everywhere I find it. A resource suck and bad for the planet.

Any help appreciated.

I installed Firefox yesterday, and everything was fine for a day. Today, when I play a YouTube video, the entire page freezes - I can't pause it, select text, or do anything. The page starts responding after about 10 seconds from last interaction.

Compared to Chrome, I can play 20 YouTube videos at once and everything works fine.

The problem only occurs on YouTube. Sites like CDA and Jellyfin work fine.
