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.

Hey, so, I've seen this question a couple times when I searched, but (a) there didn't seem to be any solution and (b) they were all regarding Macs and I'm on Windows 11 v 23H2. I keep getting bubbles saying that Firefox wasn't able to check for updates- not that it couldn't download or install updates, but it couldn't search for one. I also did the "about Firefox" thing and it gives me the same message. Both of these have been going on for a couple days and I have attempted restarting Firefox multiple times and did a manual update [125.0.1 (64-bit)] just in case there was a problem there. Now, I've tried the tips from the other threads (turning off the proxy, checking any anti-update policies, and checking the add.update.url in the config settings) with no luck. So in an effort to either bump the question or get any Windows oriented answers... Thanks muchly

As of an hour ago suddenly all of the usual suggestions and autofill with bookmarks in my address bar are wrong and out of order. I didn't close out of or update Firefox, I was just browsing online. I didn't change anything in my settings or have opened that up in days at the minimum. I cannot figure out how to either revert back or tell Firefox to not show me these choices so I can get my old ones.

I'll give an example: When I typed in "ma" it would show me mangadex.com, which I often go to. Now when I do it not only is 5th on the list it shows up and fills in "https://www.manticgames.com/", which I don't have that specific page bookmarked. I have "https://www.manticgames.com/games/kings-of-war/" bookmarked, but not that homepage. But now all of a sudden it is showing me the homepage of that site when I begin to type in "ma".

This is incredibly irritating and I have no idea why it's doing this at me out of nowhere. I don't want about anything showing up besides my bookmarks and specifically only the pages I bookmarked.

Dear all,

We develop a system on D365 platform. On Chrome enviroment, I click the export option, it will download the excel file, I can open it on Excel. However, I click the export option on FireFox, it will download the excel file but I can't open it on Excel. When I use the notepad to open the file to see the content, I found the file become HTML content. I can see the file on web broswer. I don't know why the file content will be change HTML content when I use the Firefox to download it.

I have the latest FF browser. I'm not using any proxy service, just spectrum connection. when i try to access my credit union account, i get this message

"Error: "WWF2TUh4dnM=" - You're using an outdated browser or are using a Proxy service which is unsupported. Please update your browser or turn off your Proxy to continue, thank you."

how can i get past this? All help appreciated!

I'm using the OneTab add-on, Enabled. The icon no longer shows on the Toolbar, though it is on the Menu bar next to Firefox View.

I ran Remove and then Added it again, hoping the Toolbar Icon would reappear = no go, And I lost all URLs already saved, stupid me. To be clear, clicking the Icon on the Toolbar saves all open tabs.

Is there a fix via Preferences? Thanks. gw

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.

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!

I have an iMac with Sonoma 14.3.1 with Firefox 115.9.1 esr . It is for personal use, not for a business. I just learned that there is another Firefox version (124.0.2) which is not esr....

Which version should I use and why?

If I should use the "normal" version, how do I replace the esr version with the "normal" one ?

Thanks.

In the Firefox settings, it says "Account disconnected" so I click the sign in button, it opens the Mozilla website, and I successfully sign into my account online. Yet the browser still says disconnected. I've tried a few times. How do I fix this?

I am watching a Twitch video on Firefox. When I open a new Firefox tab and drag it to another monitor, the Twitch video skips forwards about a minute.

I also occasionally notice skips or pauses when I switch from one tab in the same window back to the Twitch playing tab.

Is there any way I could fix these problems?

Hello,

When I go to update Firefox through the settings > general > firefox updates > check for updates, I am getting the error in the title. I can manually download the app installer and update to the most current version which is what I did for version 125.0.1, yesterday.

I have tried uninstalling and reinstalling firefox, installing the beta branch, refreshing firefox, running in troubleshooting mode, completely deleting all user firefox files, and I still get the error. No DNS resolver issues to the update server. No firewall issues. No network blocking (tested with other devices).

This issue started after March update to 124.0.1 and continues to current stable release 125.0.1.

This issue also seems to extend to checking for extension updates.

Below are browser logs for when i try to check for update or update extensions.

Prior to update 125.0.1 corporate intranet users could download PDF files from our Line of Business applications / Webpages. Today after the latest update the PDF files download but are corrupted. The site was added to the trusted webpage without improvement.

Adobe Acrobat Reader could not open ********.pdf because it is either not a supported file or because the file has been damaged

I just got a chromebook! Details:

Device name: Lenovo Flex 3 12.2" chromebook, 8GB ram. Intel N100 Device code name: IP Flex 3 CB 12 (pujjo, version 123.15786.0) Firefox version: 124.0.2 (flatpak) OS version: Version 123.0.6312.112 (Official Build) (64-bit) Chrome: Version 123.0.6312.112 (Official Build) (64-bit)

When I watch a youtube video with chrome my cpu usage is 20-30% When I do the same with firefox my cpu usage is 50%

Running `about:support` and going into `webrender_compositor` I get the following errors under `env`: 1. Blocklisted by gfxInfo 2. Blocklisted; failure code 3. FEATURE_FAILURE_WEBRENDER_COMPOSITOR_DISABLED

I have set almost all these force renders = True and even granted gpu access to firefox flathub but still no difference in performance. I am asking now because I am just going in circles in the rabbit hole.
