All of a sudden, Twitter will not let me log in on Firefox (Windows 11 laptop). It works on my phone, tablet, and other browsers. When I try to log into Twitter on Firefox, I get an error saying "Oops, something went wrong. Please try again later. " I have already tried updating the browser, clearing my cache, and clearing my cookies and I'm still having the issue. What can I do to fix this?

First image shows me using a dark theme, but address bar still has white background. Second image shows that switching to the light theme makes the text readable. However, I would still like to use a dark theme. I believe I started seeing this issue right when Firefox updated itself to version 100. Any way to fix the bugged address bar color? None of my extension should be affecting the address bar color.

I'm using office365 mail and I cannot drag a file for mail attachment. This works fine in other browsers and I haven't been able to find a way to do it. I really need to do this for my work, so I'm starting to use another browser, which I didn't want to.

Please tell me how to STOP the annoying Total Ad Blocker advertisements that continually show up on my screen when I am using Firefox. It's COMPLETELY ANNOYING!!!!!! I do not want to purchase this software now or later, but I will stop using Firefox if there isn't a fix for this issue. Yes, I am THAT frustrated. Thanks Steph

Unable to log into my Citizens Bank account. I keep getting an "Access Denied" "You don't have permission to access "https:citizensbank.com/HomePage.aspx" on this server." Tried updating Firefox and Troubleshoot mode.

Hi guys:

I use Firefox on a Mac (Big Sur OS), and all of a sudden when I updated to the latest Firefox version -- each time I click on Firefox it opens in a new window other than the one I'm working on which is **really** annoying! What can I do to prevent this? Is there some adjustment in preferences I'm not aware of? Please help!!

Thanks much,

Kelli

I can only save (not open) Gmail attachments after the latest update and JPG is not showing up in my the Applications section of Settings/General so I cannot fix it.

This has happened one time too many guys, every update but this time half the items I would normally get as an attachment are no longer listed in the applications menu.

If I cannot get a fix quickly I will be forced to move to Chrome (which I REALLY hate the idea of). I see 25 - 80 emails a day and it is mission critical that I can open and view email attachments without having to save them.

A little help??

Google Chrome is closed and ive checked task manager to make sure that its not open in the background.

I choose my main account from google chrome and choose to import passwords and bookmarks and it says that it successfully imported it but my passwords and bookmarks are not showing up on mozilla.

I have seen this in some past versions of FF It usually goes away after a few upgrades

Instead of whatever it's supposed to display, you can see that it shows some random characters.

Annoying. I dont even remember what it's actually supposed to show

Hi, yesterday I noticed a blue color in the menu bar tabs when I hover over them with a mouse. If I'm not mistaken, it used to be light gray before. How do I change it back?? It looks terrible and the tabs are barely readable when highlighted in blue. See the screenshot.

Hello. With version 100.0 came multi-language spellchecking. I would like to know how exactly does it work, please.

For instance, if I enable both English and French, will it simply virtually add the two dictionaries and use the resulting combined list of words? Or will it try to understand if a paragraph or sentence is English and mark non-English words in that paragraph/sentence as incorrect even if they are French?

I am obviously asking this because there is no detailed information at https://support.mozilla.org/en-US/kb/how-do-i-use-firefox-spell-checker.

please take off the red add, the pop up total add sign that keeps popping up asking to paid for the add block I am 82 and on a fixed budget. I do not want this service. How do I get it off my computer. When I want to print an article from an e mail.I always have to remove it to save an e mail, or when I want to print an article, I read it later, and I see the total ad block on my printed article stuck on the printed page blocking out what I printed. Its very annoying to have to take it off the screen before I print anything. Please help me. George at [removed email from public]

I have completely separate bookmarks and bookmark toolbars on my work PC and home PC. I do log in on my home PC as to not lose my personal bookmarks and passwords. I accidentally logged into Firefox at work and it merged my bookmarks from my home PC. I logged out of Firefox on the work PC and removed the bookmarks that were imported from my home PC profile. I then tried to make a new account with my work email and login to sync on my work PC but it always says primary email needed and I'm stuck. I did go to about:profiles and add a work profile but that doesn't help me. I need to make a Firefox profile on my work PC with my work email address but the primary email thing gets me. Is there a way to do this with my current work PC bookmarks not lost? Thanks

Hi Firefox, thanks for a great browser.

Could you please help unlocking the account for [REDACTED BY MODERATOR]

I was busy logging in to Firefox (today's update) using my account and wished to store my login info, but the link upon login was a long useless address specific to the post-login screen and related to adding more devices. I opened a new tab but this was, apparently, a sticky login and the new tab was logged in as well. I logged out of that tab with the obvious (hindsight) effect of interrupting the previous tab/s.

Long story short, the immediate effect was the message in the subject line of this mail. Firefox locked my account and I need it unlocked.

Thanks for your trouble. Kind regards Jacques
