Diễn đàn hỗ trợ Firefox

Every time I open Mozilla browser, it crashes right after it opens.

This only started happening since recently. Before this, I haven't faced this issue while using this browser for year(s)

I have failed to resolve the issue with the following methods:

• Updated Firefox
• Tried to use Troubleshoot Mode (crash still happens)
• Uninstalled Firefox, deleted additional files and re-installed
• Did Refresh

Other browsers are working fine

I am using Razer Blade RTX 2070 Max Q, VR Ready Graphics (8GB GDDR6 VRAM) 10th Gen Intel Core i7-10750H Processor 6 Cores/12 Threads, up to 5.0GHz

Firefox browser, Windows 11, window is minimized to task bar, and will not maximize to screen. Uninstalled and reinstalled, that worked for a few days. Drilled into profile, renamed xulstore.json. Worked for a couple of days. Did that again today, restarted, still cannot use Firefox. Will be forced to transition to Edge if I cannot stabilize Firefox.

I was trying to resolve a graphics issue with Firefox and Webgl2 on a specific website, so I used a recommended solution in advanced settings, which just spread the problem to other websites. I wasn't really sure what to do at this point, so I tried to just reset all the modified settings to attempt to get back to the first download settings. However, I was unable to do this and now Firefox can't load any pages, even when I've deleted the browser and redownloaded it. How can I get a completely fresh download, or even can I? I'm not tech savvy and extremely frustrated at this point.

Firefox will not open most websites, other browsers still open them. Current version of Firefox v121.0 64 bit. Problem started maybe 2 to 3 versions ago. At this point I cannot use Firefox at all, but I really prefer it to any other browser. Please let me know what I need to change in settings or Please repair Firefox soon.

Thank you

i now keep getting a pop up window saying that this profile was last used with a newer version of this application. Please create q new profile. what am I to do?

I recently noticed that fields on all Web sites I visit have an extra horizontal line at the top of the prompt. Please see attached image. This only happens on Firefox. Other browsers don't have that behavior. How can I restore the normal prompt of a straight vertical line?

Thank you!

Why does your Browser use up so much of my CPU & have all these unknown processes going without my knowledge??? It's slowing & unnecessarily overheating my gaming laptop! What can I do 2 kill all ths extra, unwarranted activity of your Browser?!? Plz help!?

Hello, Ive recently switched my primary browser from opera GX, to Mozilla Firefox. Since then I've adjusted the settings to my liking, one of which was the search engine. I chose google chrome, and it works when I open a new tab, However, When I open a new window of firefox, it always opens Bing. This is a small problem, yes, but its simple issues like this that dissuade me from wanting to use firefox at all, I would like to solve this issue, but Ive searched for answers, and there aren't any. If you help me fix this, I will keep firefox. Otherwise, I'll chose a browser that gives me the amount of control that I want. I've also attached a photo of the startup screen of firefox.

I need to be able to access banks, specifically USB Direct. I can access my credit union but when I try to get my statement, I get a message that I have been logged out due to inactivity.

its the browser, the opperative said when I phoned in about no access. try chrome, they said and true enough it worked. Just shy of 15 years with firefox and now nothing but problems, the cut and paste does not work and now this! pointless staying with them

Logins and passwords are missing. Noticed this when websites that I commonly use were not auto filling. There must have been more than 100 entries in my Logins and passwords folder. Now only 25. This is on Windows and iphone where I use Firefox.

I am running Firefox on a Windows 10 computer. I have had little-to-no problems with Firefox before now. Since this morning, every time I open Firefox, it almost instantly crashes. Even after refreshing it and reinstalling it a few times, the problem persists. I have no idea what the cause is; I don't remember drastically changing any settings or anything like that. It will crash even when I use safe/troubleshoot mode, when I open a private window, and when I run it as an administrator.

I got to a point where it would give me a sliver of time before crashing. Following the advice of a Firefox help article, I managed to clear all of its stored cache and cookies(if I remember correctly). Still no fix.

If anyone knows how to fix this, I'd love to hear the solution when convenient for you.

Dear Mozilla/Firefox, in the past week or so Firefox is noticeably slower to load than Norton Secure or Google Chrome. Running from a shortcut or pasting the same link into the address bar, Firefox takes around 25 seconds to load where Norton is almost instant. There are features of Firefox that I prefer over other browsers so hope you can guide me how to fix this. Thank you,

Can not login to my PNC Bank after Firefox update 121, another computer could ling in until it to was updated by 121. I can login with Edge. Windows 10 (up to date), 64bit, Intel(R) Core(TM) i7-5930K CPU @ 3.50GHz 3.50. I get, see attached screen shot, only when using Firefox 121.

After years of Firefox, suddenly I cannot start Firefox. It crashes in less than 5 seconds after I try to open it. Safemode did not help. Reloading Firefox did not help. And I certainly need my bookmarks and history. I have no idea why it is suddenly happening. i am on a Dell Desktop, windows 10, 64-bit machine. Both Malware Bytes and Norton show there is no malware.

Up until today video on youtube played fine. Today I can hear audio, but the scree is just green. Trying to fix myself, I read change preferences in Fire Fox. But I can't figure it out. Bitchute and Rumble play fine. I reset my desktop by turning it off. Same with closing down my browser. No help there.
