Firefox Community Forum

I used to play World of Tank and look at YouTube on my second screen. Everything went smooth untill this week. YouTube on Firefox on my second screen is lagging or freezing. I tried Opera, I tried Edge it worked fine, but with Firefox, it is no more possible to play YouTube on my second screen while playing. It is not a matter of graphic hardware as this issue only happen with Firefox. I tried to deactivate every module and to reinstall Firefox (either the Beta version) but still got the same lagging and freeze on YouTube. Do you need anything that can help you to investigate this issue, this is really terribly frustrating and boring.

I've synced all my data (including add-ons, passwords, bookmarks, etc) to my firefox binded account on fedora linux then change my linux distro and re-setup firefox on Manjaro KDE, login and etc

found out that everything synced but my previous add-ons and open tabs are gone for good I've so many opened tabs are my custom add-ons settings on so many add-ons for personal preferences are gone

I've faced this many times but I thought somehow these days firefox might have fixed these issues but i'm so sad that all my important data are gone :(

I'm using firefox only just for sync+privacy for hassle free setup again and again over many devices otherwise i prefer tor for much anonymity and privacy

PLEASE, YOU GUYS CONSIDER WORKING ON SYNCHRONIZATION FEATURES SPECIFICALLY <ADD-ONS> AND <OPEN TABS>

thanks for reading and pl igonre my english errors

On my new Scorptec rtx A2000 workstation installed Firefox and Thunderbird and for 2days everything was fine apart from the annoying notice that came up every time I opened Firefox as me to make it the default browser ,which i turned off. however about the next day another window appeared in upper right corner of the screen that looked very authentic with the Firefox Logo and screen colors which stated that I had not yet fully activate all options in Firefox. on opening it there were 4 options to tick off .

First was making it default browser which ticked

Then there were 3 highly recommended extensions with reviews of each and a quoted number of users that highly recommended them second was enabling an Anti Key stroke Logger app which I ticked third I think gave them full access to PC which I ignored Last i cant remember but I ticked as it looked harmless. Within an hour the Firefox screen turned white and was activated by

quick-hp.com//?path=firefox/  then more info etc.

Just incase the have installed a key logger etc have decided on full removal and reinstall of win11 etc Be Warned

path=firefox/.........etc...etc

Firefox is creating very high CPU use with many WebThumbnailExtension Web Connect processes. The processes disappear after shutting down Firefox and other programs that access the internet. Does anyone have an answer on how to prevent this from happening?

I lost my old computer and now I need to recover my Firefox bookmarks. I was using Mozback. I reloaded it on the new computer but I cannot get it to restore using my backup file (.PVC). Is there an alternative available that I can use?

I am in Denmark and would like to get access to https://sede.mir.gob.es/opencms/export/sites/default/es/inicio/ when I press Access throug digital signature, It says secure connection failed. To be able to access spanish government sites with my spanish digital signature how to get firefox to approve it? I was tried to add the websites and approved but didn't work. The certificat is installed correctly and tested when I was in Spain. Thank you for your support.

OK seems mozilla will continue support for firefox 115.20.0esr on my WIN7 machine, but not my 115.20.0esr on my Ubuntu 24.04lts machine after next month - why? (128esr and 135 are both unstable on my laptop's Ubuntu 24.04.2lts for some reason - constantly crashes, freezes up req. cold boot, or just logs me out - pain in the... even after upgrading 2Gb RAM to 4Gb)

OK seems I can upgrade (don't know why they keep calling it 'update') my Ubunut 24.04lts machine's firefox 115.20.0esr to firefox 128.3.0esr, but not on my WIN7 machine -why?

i.e. why does firefox give preferential treatment to WIN7 for 115esr, and preferential treatment to LINUX for 128esr ... why not both OS's on both "esr's"

...makes me go: hmmmmmm ;-\

I have been unable to access Yahoo Mail for a week now. When I attempt to sign on I get this message "Something's gone wrong We may be having trouble with your connection. Connecting your device to Wi-Fi could help fix the issue or try again later."

I have no problem when I sign in with Google.

We apparently lost power sometime during the night. When I turned on the monitor and opened FF, I got the error message that it had crashed. As my subject line says, I lost all my tabs, the pinned ones (probably about 10) as well as the open ones (probably between 10 and 15). I also lost all my history. I can't use the 'Restore Previous Session' because it doesn't give me that option.

I've restarted Firefox and also rebooted my computer...still nothing happens. It's up to date, version 133.0. But I have no history beyond this morning. Is there any way I can recover those tabs or history?

And in my FF Settings, there's a link at the top that says "Your browser is being managed by your organization". I don't have or belong to an organization. When I click on the link it takes me to another page that says it's "Active" and there's a huge list of "Documentation" that apparently involves a lot of code. Can you please explain what all that means? Thanks so much for any help!
