No longer able to copy or paste text on Firefox with Windows 10. Copy and Paste are greyed out in the right click menu after selecting text. Using CTRL-C, V or P does nothing at all. Still works fine in other browsers. What has Firefox broken again this time?

Since a day or two the font size on my Menu Bar is way too small. I have been searching around and the solutions are not working or not what I want. I do not want to zoom in, I want my page size to remain the same, I only need the font size on the menu bar back to what it was. I tried the userChrome.css method and it did not work

What happened to "recent bookmarks"??? I is no longer available....why???? I need it back, as I used it all the time and my bookmarks were very easy to locate. Now I have no idea where a bookmark is, that was even bookmarked an hour ago.

Firefox stopped working with my VPN on when I updated my OS to Sonoma, yesterday. I use PIA for my VPN.

I have done the following, so far, restarting my system several times between trying these things:

Checked that internet connection and modem are fine. All pages load in Safari, with VPN running, but I prefer Firefox.

Checked the Network settings for my Mac. Ensured that No Proxy was selected.

Cleared my Firefox cookies, cache and history.

Tried running in troubleshooting mode, turning off all extensions.

Tried turning off Advanced Tracking Protection, which I usually run on Custom.

Refreshed Firefox.

Finally, I turned off my VPN and, viola, all sites work. Turned it back on, and can’t navigate, again. For instance, I tried to open YouTube, and got a blank screen. Turned off VPN, and got to main YouTube page. Turned the VPN on and tried to log in…nope. Turned it off and logged in. Turned it back on and tried to open a video….nope. Turned it off and opened the video…etc., etc..

I very much wish to continue using both Firefox and my VPN. Can you suggest a course of action? Thank you for any advice you can give!!

I have a very fast internet connection, 200 mbps and everything else on both my laptop and my mobile phone are working fine but Firefox is very slow. Pages load ok but videos will play for a short time and then freeze never to continue and downloads are painfully slow, 2 to 4 mbps. Edge and Chrome download normally and videos play with no issue. I need this fixed or Firefox is going bye bye!

Hello, dear Firefox Help people!

I keep a lot of tabs open in my Firefox browser (121.0 64-bit for Windows 10). Starting just recently, if I closed Firefox by clicking on the "X" in the upper-right corner of the window, then the next time I start Firefox it opens without my tabs! (It never used to do this before...) It's very disconcerting, but I found that if it starts up without my tabs, Ctl+Shift+N will open Firefox in another window--with all my tabs! I can then close the original window (the one without my tabs), and go on using Firefox in my normal way.

If I have Firefox running with my tabs present, and I close Firefox by using Ctl+Shift+Q, the next time I re-open it, all the tabs are there. (That's also the case when I close Firefox using the three-line menu and "Exit".) But I used to be able to close Firefox by simply clicking on that "X" in the upper-right corner of the window, and next time I started Firefox it would open with all my tabs intact. I'd like it to work that way again... What must I do to get it to return to working that way?

(Please note that under Settings/General/Startup, I do have "Open previous windows and tabs" checked...)

Thank you for any help you can provide...!

Okay, I am unable to get into my bank online even after doing steps to fix Error code: PR_CONNECT_RESET_ERROR checking the site, it says this is at firefoxes end

When I open Firefox on my new computer all the bookmarks are showing at the top. I only want my default bookmark toolbar to show. The only solution I could find was to drag it into the toolbar area.

I'm trying to give permission to a website to use my microphone, but if I copy in the web address, the "Allow" button doesn't appear & so when I hit "save changes" nothing happens.

When I load www.foxnews.com a popup box comes up and says to view the news to turn off my ad blocker, and then makes the site inoperable. I can't find an ad blocker so I'm thinking I might have a security setting wrong. I can view the website in Chrome with no problem. Any help is appreciated. Gary

Hello everyone. Well, I've been using Firefox for a few months, maybe a semester now, I don't remember. But the point is that since yesterday I have been facing a serious problem of not being able to download any type of file (MP4, PDF, .JSON, ISO, etc.). I've already used the troubleshooting mode and I've also restarted my laptop, but it didn't help. I've also gone to the advanced settings (see 'about:config > browser.download') and reset/deleted the data for each command but the problem still persists.

What happens is the following: I click to download the file in question, however, nothing happens other than the page loading that commonly occurs when downloading something. Still, the file does not appear in the downloads tab and there is not even the option to choose where to save the file (e.g. Downloads folder, Documents folder). The download simply appears to have failed.

Exactly, it 'appears', because today I discovered that all my downloads were being directed without my permission/action to the 'downloads' folder (And that's not where I want them to go). The problem would be smaller if only this happened, as I would then just get the files downloaded there and then change to the desired folder, thus trying to move forward despite the problem. But the downloaded files themselves are not operational, they have the icon when a file is still downloading, in addition to not having a name, everything being just a cluster of codes.

In the end, there are files, large and small, that have no use and that I don't even have control over where to direct them. Which is still a huge problem because I still technically can't download anything from the browser. Please, I really need your help on how to resolve this problem.

Note: Also, when I close and open the browser, the first download I try appears in the downloads tab, but it fails instantly and cannot be resumed, making it an eternal failure.

Hello, I want your help! Because I want to change the appearance of checkboxes to toggles without affecting the other checkboxes (like rounded checkboxes) using userChrome.css in Firefox.

I'm not friend with CSS, because I don't know much about programming. So, please write me a correct CSS code in a comment.

The attached screenshot will explain my demands:

After the last couple of updates Firefox will not wrap words in view source screen(CTRL+U). This makes the info very difficult to read as most lines of code run off the screen. How do fix this? Thanks.
