Firefox Support Forum

So I was setting up Firefox and accidentally imported data from a different browser than I intended to and I don't know how to remove all the bookmark and auto fill that I had imported. I have tried deleting the Firefox file in window explorer and it didn't work. Is there anyway to completely wipe Firefox clean?

In settings when I am in security I have Firefox as my default search engine. When I go into the search tab it tells me Bing is. There is a drop down box to change it but Firefox is not an option. Help I am also unable to get into my xfinity email so please respond to, [removed email from public] Thx

weibo.com will not load on Firefox. I've tested it on Edge and Chrome and it loads on both. It uses a "sina passport" system, I assume to handle traffic from outside China and avoid DDOS attacks. The URL for this is passport.weibo.com. The issue with Firefox is that it never passes this check. The passport will continually refresh and never load the main website content, only serving a blank URL as it tries to enter the site.

Dear Mozilla

I wrote to you earlier today about a problem i am having with themes.I change themes quite frequently and have a lot of them on my list. After opening and closing the browser once or twice the list of themes no longer shows what each theme looks like. I reset Firefox and the image of each theme reappears. It's quite tedious as i said to have to do this once or twice a day. Is this problem occurring because i have too many themes on the list?. I have turned off all other extensions and the same problem keeps happening. I don't know what to do.

/edit: Please put a space after periods as there were unintended links.

Prior to getting some desktop PC upgrades that required a new install of Windows 11 and a new install of Firefox, I backed up my entire PC (yea!).

Now that I have re-installed Firefox, I see that I have none of my saved bookmarks and so I want to restore the Firefox profile - all of it or at least the bookmarks.

I have tried following the Firefox instructions for this, but am apparently not doing it right.

I can't seem to locate the bookmarks file, for starters, in my backed up files. I find the profile but I don't find anything like places.sqlite.

Can someone help me so that I am locating the right (and complete) files, copying them correctly, and then switching to the new/old profile correctly?

Thanks in advance.

The free virgin.net email service was shut down without notice about 2 years ago so I can no longer receive the verification code to cahnge it in my Firefox account. Is there another method to change the email address registered with Firefox?

After downloading Firefox browser from my organizations toolbox on my new enterprise Macbook Pro, I logged in using my email address, but my password was not recognized. After resetting my password and successfully logging in, none of my previous data is available. Is there a way to find this data from my last back up? I do have my Mozilla recovery key.

I'm belarusian and I'm using belarusian, polish and english languages on internet, also I have somehow russian language??? I can't delete It from my language preferences, how can I delete russian language from my language settings fully?

My previous version of Firefox was on the fritz and I was afraid there was malware in it so I uninstalled it. When I reinstalled it I realized all my bookmarks were missing and I can't figure out how to restore them from my profile or a previous backup. Please help! Thank you.

Simply help me find how to double space. It is not obvious.

I started using Apple computers in 1980. A university professor, i urged my students to buy, Mac, even though the University was committed to the other.

I am forgetting things I knew relating to computer, in this case. Your Support site hides 'Double space' why? John Klassen

I had something like 7 windows open 10 minutes ago (yes I am a tab hoarder). I was trying to run a game that used a lot of RAM, so I decided that I would close ALL of my firefox tabs in hope that the game would run smoother with the 5gb that Firefox was using. I didn't think anything of losing the tabs because I had accidentally closed windows in the past using the big red 'x', and an easy ctrl + shift + t always restored the entire window no problem. When I tried to open firefox again within the next 5 minutes, only 3 of the windows restored themselves, I assume using the general > startup > open previous windows and tabs setting. Using Ctrl + Shift + T did nothing to restore them. Please help, as the windows that did reopen were the ones that I cared the least about.

1. When I click on the Firefox "password manager" it takes me to "install Firefox". Is Firefox one in the same?

2. How is the Firefox password manager different from RoboForm?

Thank you!

i yug yadav lost all my data and when i reset my password all my history ,bookmarks and passwords are not unable..kindly do the needfull for recovery of my previous data of my id ...[edited] @gmail.com..so that i can able to get my passwords and bookmarks ..on this device again

I have just had a new update 115.0.3 and again it has blocked most of the internet sites (all working yesterday no problems) due to secure connection failed.

Error code: SSL_ERROR_NO_CYPHER_OVERLAP

This is about the 3rd / 4th time it has happened this year alone.

Are you not able to produce an update without blocking over 80% of internet sites when updated?

The strangest thing is other browsers are able to connect to all of the sites.

When I log into my TD financial account, I always now get the message "Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit", and I crash out of my site. I will even sometimes get the message when I log out. What's going on? When I log into my TD account using Microsoft Edge, I don't have this problem. After years using Firefox with no issues, now I have this these last few days. What's going on?
