Firefox Support Forum

After the latest Firefox update (121.0.1) , I have been unable to use Firefox to log into iCloud or my Merrill Lynch account. I have to use Chrome instead. Other website log-ins seem to be ok.

I am facing issue while downloading files in Firefox Private Browsing. Whenever I download my PDF files, as soon as I close the browser window, the files also get deleted automatically. What should I do to rectify this issue.

As of this morning, the Firefox browser on my work computer does not get access to any website - including mozilla itself. On the same computer Safari works without problems, on my smartphone and in the same wifi network my mobile Firefox works.

What is wrong?

I got a new Acer laptop with windows 11 (64bit). I downloaded FF but when I open it, it just gives a blank page. If I type in an address nothing happens. I have tried reinstalling but nothing seems to work

Scrolling in Firefox is causing any webpage to scroll many lines at once with a single click, and it seems to be exclusively happening to Firefox, as every other application scrolls normally. I have tried searching here and elsewhere for a solution, and I have tried to change about:config settings based on the recommendations I could find to no avail. I have also tried to refresh Firefox and have used Troubleshoot Mode, but those too have not worked. I have no clue as to what could have caused this, as I have not been messing with any settings prior to this.

Well, I have applied all the options about proxy settings with the same result of long time for opening websites when first start of firefox. During these months I took notice to the one point, i.e. if I open website using firefox in the earlier morning there is no problem with the speed of opening as well as if I open another browser of edge the last one opens website without any delay. So the challenge of long time opening websites when the first start of firefox is still in force. How to resolve this?

Hi! Yesterday i updated my firefox to last version and i got my UI way too big, so today i looked online for some fix on that. I found a fix saying if you add a line in about:config site with the parameter "ui.textScaleFactor" with a value of 100 it will be fixed. but by mistake i changed it to 10 insted of 100 so when i open firefox i have a super big black screen

most of my problems are i can't reinstall firefox because it made the same weird big ui problem. There is any way to fix it?

thanks in advance

Hey everyone,

I've been encountering a persistent error with Firefox, and I'm hoping someone here might have a solution. Whenever I try to open Firefox, I keep getting an error message that says "Secure Connection Failed" for certain websites. It's really frustrating because it's preventing me from accessing important sites. I've tried clearing my cache and cookies, but the issue persists. Has anyone else experienced this problem, and if so, how did you resolve it?

Thanks in advance for any help you can provide!

I just "refreshed" firefox after it stopped loading all the websites. I then tried to isolate the problem, found out that there is no issues with my firefox and any of its add ons. But as soon as I add Chrome folder and a css to enable multirow bookmarks folder. No website launches. Just white screen. Anyone experienced the same?

Please help as I really need multirow bookmarks. Thank you.

It turns out the copied logins-backupjson file i had pasted on my desktop screen was already overwritten by an added or removed login, thus writing over when it did have the saved login removed that i was trying to recover

is there any other way to recover the removed login?

i saw this response by Cor-el for another user with a similar situation

If you still have the signons.sqlite that was used in a previous Firefox version then you can try to restore passwords saved in that file.

Firefox 32 and later builds store the passwords in the logins.json file in the profile folder and no longer use the signons.sqlite file that has been used before (the matching key3.db file is still needed). If you still have the signons.sqlite file used in previous Firefox versions then you can try to force Firefox to migrate the passwords saved in that file (you will lose passwords saved in Firefox 32+ versions). You can force Firefox to reimport the passwords from the signons.sqlite file and rebuild the logins.json file with these steps:

   reset the signon.importedFromSqlite pref on the about:config page to the default value via the right-click context menu
   delete the logins.json file in the Firefox profile folder with Firefox closed 

When you restart Firefox then you should have the signon.importedFromSqlite pref with the value set to true and you should have the passwords imported in the Password Manager unless there may have been errors.
