After updating to v 133.0, when maximizing Firefox (not F11 fullscreen), a taskbar that is set to "auto-hide" will no longer unhide when mousing to the bottom of the screen. This did not occur with the previous version (132.0.2).

This behavior is also unaffected by the "devtools.toolbox.alwaysOnTop" setting in about:config as i've tried switching from the default "true" to "false".

Update: Still persists in 136.0.2

For some reason, IDM will not work in Firefox/DuckDuckGo. even though it worked a couple of weeks ago. I contacted IDM support who have tried everything they have, but no change.

Here is the issue: 1. I open Firefox (Duck Duck Go is my default) (132.0.2 (64-bit) 2. I type "vintage sci fi movies" 3. Click on "videos" 4. Pick any movie (example: The Phantom Planet (black and white but this does not matter) 5. In the Choose How you Watch, I click the left icon - Watch Here, and not Watch on YouTube; also click Remember my choice 6. The movie starts but there is no IDM dialogue 7. If I then click Watch on YouTube inside the movie, it switches to YouTube and the movie starts, AND the IDM dialogue pops up.

As I said, this worked in Firefox/DDG a couple of weeks ago.

IDM version is 6.42 Build 23, full (paid for) version Oct 15 2024 The IDM Integration Module in Firefox shows as Version 6.42.22, last updated Oct 28 2024.

Can you assist please.

Firefox is verified Broken! Whatever Firefox did with its last update is causing major problems. Spent hours with the internet provider and websites trying to figure out why could not access webpages and internet accounts.

Firefox is taking forever to load pages and often just times out or never actually loading the page. When I can get to a page, something is interfering with account access on webpages. Spent 3 hours with AT&T where they monitored trying to access my email account.

Could access with Edge, Chrome and Safari. However, Firefox is dead and will not allow me to access websites as pages do not load or interferes with account access.

Mozilla support needs to fix this issue ASAP or I will be forced to leave Firefox for good. I know I am not the only one having this issue! I was willing to put in the effort to verify if Firefox was actually broken or not!

I thought it was an issue with my pc, but chrome does not have this issue and neither do other applications. I have tried clearing my cache and cookies as well as ensuring mozilla was using my computer performance settings as opposed to hardware acceleration. The attached images are a very small example of the issue. Typically, after clicking on the screen or pressing a button the text is corrected but often replaced with new text being "corrupted". Any help would be greatly appreciated.

Even though CPU and GPU utilization is very low during 8K60fps Youtube playback in the Firefox browser on my base M4 Mac mini, the struggles heavily to play this, drops tons of frames, and the video almost stops playing.

8K 30 fps is not problem, and since utilization is pretty low, that doesn't explain the poor performance.

So please optimize 8K60fps Youtube playback on all platforms in the safari browser, but especially on Apple SIlicon Macs.

My Firefox on windows 10 crashes tabs OFTEN. Mostly is seems to be Facebook and YouTube tabs, but other tabs will crash and this morning, the Firefox start page tab crashed. I've done "refreshes", I've uninstalled and deleted the folder and re-installed, I've checked the SSD for errors. Nothing appears in the event viewer. Is there some way to definitively figure what is causing this?

I can not get into my Yahoo Email account. When I log in it says, "Something's gone wrong".

I can get into my Email through a different browser on the same computer. This started last 

Wednesday (01-29) or Thursday (01-30). Help.

Thank you for your time. Tony S.

Hello I've been a Firefox user for decades; recently a problem suddenly appeared that I'd never encountered before; I mentioned it to you but you didn't see fit to reply. I have twice 'repaired' Firefox, to no avail. After hours of Internet research, I've discovered the nature of the problem: it's called FirefoxCP Isolated Web Content. According to the many forums I've consulted, you're perfectly aware of it. So I don't understand : - why you don't take the trouble to reply to a user with a problem. - and, above all, that you're perfectly aware of the problem and don't do everything in your power to solve it. As 'killing' an activity in my Mac's activity monitor every ten minutes is rapidly becoming unbearable, I'm going to have to change my browser, much to my chagrin. Farewell dear Firefox!

I often receive a 403 error when using Firefox Every time, before this happens, I get the unsafe website warning and then the 403 error when I continue anyway

I am using the latest version at the time of writing These errors only occur on my desktop PC I have tried to replicate this issue on both my phone (Android) and another laptop(Windows 11) but all the websites work normally on there.

I have tried the following, none of which have any effect:

• Clearing cookies
• using Troubleshoot mode
• Restarting
• Changing Useragent
• Using "Forget about this site"

The following do fix the issue

• Using a VPN
• Using Google Chrome
• Running Firefox in another profile

Going through the privacy and security tab and reseting all the settings sometimes works but only temporarily

The following are a few websites where the issue occurs

to get access to my bank account via Firefox the bank should send me an access code on my mobile. The page pops up on Firefox, I wait for the code but there is nothing coming onto my phone? I can access my bank via a different website so am wondering if there is a problem with Firefox. By the way, my mobile functions correctly and I receive calls.

I have struggled with logging into E*trade using Firefox with no real solution other than clearing cache and cookies each time. After downloading No Script extension, I have identified adobedtm.com to be the cause of the eternal white page hangup when trying to access E*Trade. Wanted to make this info available in case a fix can be made without the extension.
