Firefox Support Forum

I've tried going into Full Screen mode three different ways:

• Clicking the green MacOS button in the upper left of the window
• In the Firefox menu in the upper right, to the right of the Zoom choice I click the full screen icon
• Pressing Command+Shift+F

But whatever way I do it, I still see the tab bar, address bar, and bookmarks toolbar rather than a true full screen. Not sure what I'm doing wrong.

HI, I have a Mac with El Capitan OS and Firefox 78.15.0esr. Recently I can´t open some websites: ChatGPT, Likendin, TunnelBear, Wester Union, etc. Before everything was working perfect. Please HELP! Thanks friends :) When I try to open this website, nothing happens, nor an error, sometimes in certain website it keeps retrieving and thats it.

Many thanks,

I've had an ongoing issue with Firefox now for several months since upgrading to windows 11. When I try to copy text, or images, url's or anything really that is supposed to go to the clipboard, it copies a blank text with no data instead. I can copy text and images from other programs and even paste them into text fields on Firefox but I can't copy from Firefox to anything else and it's frustrating.

I recently got forced into upgrading Outlook in windows and hated it so I started using Thunderbird and surprisingly, I have the exact same issue there as well.

I have tried: Running Firefox in safe mode (Shift + Left Click) Resetting Firefox Switching Back to default themes Disabling hardware acceleration Updating to the latest Beta Build (v126) Running Firefox Developer edition

I really want to get this fixed and working, I don't want to have to switch to another browser =/.

Hi there,

I need to be able to use Command-I (for italics) or Command-B (for bold) when using Firefox to write emails and enter information on other websites WITHOUT Firefox opening Page Information or Bookmarks.

This is basic browser functionality! People use browsers to write emails and other online documents, and the hotkey combo for things like Bold and Italics on Macs are Cmd-B and Cmd-I. All such websites I use recognize that as a standard, but Firefox insists on using those same commands for browser features I almost never use and certainly don't need hotkeys for.

All the information I'm finding online on how to fix this is deeply unhelpful and far more complicated than I can handle. Can you please tell me if there is a simple way to stop Firefox from pulling up Page Information and Bookmarks as a result of keyboard commands, or at least for me to change what those commands are so that they don't conflict with industry standard commands for text formatting on the vast majority of websites?

Firefox Setup 125.0.2.exe popped a flag on Jotti's malware scan: ClamAV: Win.Trojan.Spora-7724442-0 I know this is going to turn out a false positive because VirusTotal came up with no flags but can someone at Mozilla get this flag cleared at Jotti's/ClamAV ? thanks

Firefox can take screenshots of pages or screenshots of custom areas of pages.

According to the documentation, when we download the image, the filename should follow the pattern: Screen Shot yyy-mm-dd at hh.mm.ss.png. If I use the :screenshot at the console, the pattern works as documented.

But Firefox is using a different pattern when I choose Take Screenshot from the context menu. The pattern includes the page's title. Example: Screenshot 2024-04-14 at 18-35-16 General ‹ Settings ‹ Geomaster Lda — WordPress.png.

Since the page title can have non common filename characters, I have problems with such filenames. My uploads to MediaWiki fails with such filenames. I know I can report or improve MediaWiki, but my question here is quite simple.

Can I change the Firefox's default pattern for Take Screenshot's downloads?

I can no longer log into my social security account using Firefox, but the login does work on edge. When I try login on Firefox, I get the following error message:

Bad Request

Your browser sent a request that this server could not understand. Size of a request header field exceeds server limit.

The initial web site is https://www.ssa.gov/. From there I hit "Sign in", and get to https://secure.ssa.gov/RIL/SiView.action using Edge, but get just the error message using Firefox.

There is another route, which is through https://www.ssa.gov/myaccount/. Hitting either account or sign in on that page will work on Edge, but gives the same error message on Firefox.

today 4/18/2024 firefox update. Now browser is slow. Task manager showing currently 15 firefox open, even though only one new tab is selected. It is causing laptop to overheat, fan is running constantly. Nothing else is open.

I recently purchased a new Mac Book Pro. After migrating my data from my old one I noticed that when using Firefox my Facebook account was not working properly. I no longer could access my own page or the pages of friends. However, I could access some group accounts I'm associated with. On Safari, everything works fine. I suspect something must have been compromised during the data migration.

I deleted the Firefox app from my new computer and then reinstalled it but to no avail. When I'm in Facebook and try to access my page I get an error message. My OS system to up to date and apparently my Firefox is up to date as well. Any suggestions? Thanks!

Hello. In the last few days when I visit my Shopify website, the pricing on my products is not visible. This is only for me, nobody else has this issue. I do not have this issue on Safari, or on Firefox when I open a private browsing window. It is something to do with Firefox, but I don't want to have to open a private window every time I go to my store. Is there a solution? This has only been happening for the last few days. Thanks
