Firefox Community Forum

i now keep getting a pop up window saying that this profile was last used with a newer version of this application.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?

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.

Almost every time I open Firefox it has changed my screen look, my preferences and my security settings. I'm lucky if my restoring lasts 2 days. For example; this morning I opened Firefox and all appeared to be OK. This is afternoon and Firefox has come up with a dark screen, changed preferences and altered my security settings. I've raised this subject before and I'm really tired of doing this. I favour Firefox because I like the relative independence of it, whereas MS and others seem to pry on everything one does. I also think MS is deceitful in that I cannot get back my MS Office (that I paid for) after a rebuild.

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.

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.

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.

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!?

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.

Hi Support,

I have always been struggling with the idea of syncing two devices, that is main and secondary devices, and that when logged out of the secondary device, user details such as passwords, booksmarks and other important things are left bare on that browser or secondary device.

It is my believe that, after completing whatever task that led users to sync both devices, the moment the user logs out on the secondary computer, or any of the computers, the passwords, bookmarks, history and other essential details should not display again on such computer or browser anymore but apparently thats not the case with Mozilla Firefox browser.

Kindly look into that and work on it....THE SECURITY AND SAFETY OF THE USER IS LEFT WIDE OPEN!!!

When I followed instructions, it sent the login file to the flash drive I designated but in an Excel format & I don't know how to print it in a readable (.doc format). Any help is greatly appreciated. bucretired@yahoo.com

I need to pass a pc scan on my new hp all in one desktop for a new job with Arise.com It allows me to use mozilla firefoc for my pc scan, I continue to fail. please help

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

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,

When I load KRCR.com it opens. When I click on an article screen goes blank. When I open redding.com page freezes and locks up Firefox. Using Sonoma 14.1 Cleared the date but no difference

These sites open on Safari with no problem.

Any help appreciated, Don

I've been having this problem for a couple of weeks now. When I go to certain websites (that work on Every other browser I use) I get the following error:

Network Protocol Error

An error occurred during a connection to www.diamondtoolstore.com.

The page you are trying to view cannot be shown because an error in the network protocol was detected.

   Please contact the website owners to inform them of this problem.

It happens with Lowes & Home Depot - two sites I use every day for work. Now I have to use Chrome or Microsoft Edge -YUCK. I went to your help page and tried everything I could find that may help with this issue and nothing has helped. I see that there are a LOT of other people having the problem as well...Can you please fix it.
