Firefox Community Forum

Hello, for quite some time I have been encountering an issue where the scaling of browser elements gets broken when I unplug my Mac from its dock/external display and then being using Firefox using the built in Retina display. This only impacts Firefox and renders Firefox completely useless until I quite Firefox and reopen it. It impacts all open Firefox windows. The attached screenshot explains it better.

Firefox 146.0 (aarch64) MacBook Pro 16-inch, 2023 macOS 15.5 (24F74)

Any ideas?

Hi!

I've had issues with Firefox now for quite a while and they only seem to be getting worse. Performance is really bad, it's lagging while browsing, especially infuriating when typing as the letters come out at a stuttering pace. I've tried disabling extensions one by one, I've tried troubleshoot mode and experienced no major difference.

If I can't solve this soon enough I won't be able to keep using Firefox, as the experience is so frustrating. And it would be a shame since I've come to like it quite much.

Thanks!

I know this probably sounds odd but I'm not imagining it. I like many people I live with many tabs open at once. Since the 143 update I come back to my computer the next morning and many of my tabs, specifically my gmail tab and many others will not work. (Oddly I've noticed some random tabs will still work, I have no idea why) I can close the tab and try to reopen gmail in a new tab and it just sits there trying to open but it will not. I've waited 20 minutes. Not until I close firefox and restore my last session will it again work properly. Is there a bug/glitch or is there some setting I need to adjust. I don't want to have to close my firefox everyday. Edge is not having this same issue, so I'm pretty sure it's not a problem with my specific machine. It's like Firefox just decides to quit when I go to bed. I know it sounds crazy.

Firefox has been my entire family's browser of choice for as long as I can remember. Which one am I supposed to use now that Firefox won't quit shoving bloatware and diminished performance at me? I'm also seeing articles stating that they plan on making it even worse with more AI. I'm supposed to let them steal my data and turn my browser into sludge with absolutely no benefit to myself? And they're asking me to donate to them on top of it???

Does anyone know of a viable Firefox alternative that isn't a chrome dupe?

I have Firefox (always updated to the latest version) and I have noticed a memory leak that EATS up RAM. I have 1 tab open, playing a set spotify playlist. within 24 hours of rebooting the machine, Firefox has swallowed 7gb of my Memory as shown in Activity Monitor/Memory Pressure. I've been having this issue for some time, updates to MACos make no difference either. NO other program does this. I've tested the same playlist in other browsers, Chrome, Safari, uses 1gb, brave/opera uses less than 500mb and they've been open for over a week. This memory leak is a bug in Firefox. I've seen it before (other software, mainly on Windows) but never like this on a Mac......How do I escalate this?

Ever since I got 133.03 my Dell cpu freezes a lot. Over the last hour it froze 15 times. This is terrible reliability.

I hired Dell Tech Support and they checked my software and there were no issues. I have run advance Norton features and there are no problems. Therefore the issue is NOT with my 20 month Dell computer.

Firefox has always been reliable until late August. For four weeks it would freeze and lock up. by the end of Sept it was slightly better and then fine in November. Now it only freezes, put the mouse over the image and it freezes. Play with it for a while and it unlocks.

I am totally fed up with Firefox. I'll be starting my taxes soon and year end things and can't afford to have all these issues and rebooting to help eliminate the issue.

When is Firefox tech support going to help me? When is Firefox going to fix the issue? After Christmas I am looking into the Microsoft software......enough is enought!

I'm running the latest version of Windows 10 and Firefox 143.0.1.

I recently bought my first OLED monitor, so I enabled auto-hide taskbar in Windows to try and reduce the chance of burn-in. However, while it works for the most part, it seems to often break in Firefox where the taskbar will hide, but not reappear when I move my mouse pointer to the bottom of the screen.

You can replicate this issue by having FF not maximised, then dragging its window titlebar to the top of the screen and letting go in order to maximise it. At that point, the taskbar no longer pops up when you mouse over the bottom of the screen.

Many thanks for any help you can give.

Several weeks ago Firefox worked normally for me. I left for most of the day and when I got home Firefox no longer worked at all. Everything on my home page was gone and when I typed in websites - such as my e-mail program or Facebook, nothing ever came up. I'm not super browser savvy, but I opened the menu and under help was "trouble shooting mode". I didn't know what that was but figured nothing much more could go wrong with Firefox, so I chose that. I had to rebuild the websites I had in a row on the middle of the page. I didn't lose bookmarks, but everything else was different. So I left it that way.

Earlier today, Firefox wanted me to do another update. I thought maybe by agreeing to that, things might return to normal. Noooooooo. It's no better whatever. Now I don't know how to get out of troubleshooting mode to know if anything will work normally again.

I am seriously considering switching browsers, but I have a LOT of stuff bookmarked and that would be very intensive to build all those book marks in another browser.

Hi, After updating to the latest version of Firefox on my laptop, I’ve noticed that the battery drains much faster than before. I haven’t changed any settings, but the browser seems to consume more power even with just a few tabs open.

I’ve already tried:

Restarting my laptop

Disabling unnecessary extensions

Clearing cache

But the issue is still there. Is there any specific setting or workaround to reduce battery usage in the new update?

Thanks in advance!

So out of nowhere, I can't use the back button, or delete pages by clicking the 'x. I can't even click on the settings icon, or any icon on the menu bar. When I hover over any web page title, it shows a small window of it, but I can't get rid of it. I didn't change anything, so what's going on?

Gmail is slower than frozen molasses, it is taking 15 to 20 seconds to respond to mouse clicks and typing as well as scrolling, it takes me more than half an hour to do what should take a few minutes, if this is not fixed soon that will be the end of Firefox for me, I will use Opera instead.

I'm unable to do much with Firefox now.

Chrome works fine. I'm using it (unfortunately) now in order to contact you.

When using FIrefox, it starts and does some partial loading, but then stops responding. On the default Firefox startup, about 1/2 of the "thought provoking story" pictures load. If I go directly to Youtube, for example, again....it starts loading then "hangs".

I can't close Firefox either: the window closes, but it's still running. If I attempt to restart it after closing, I get a "Firefox still running" error (which also won't close it.) Windows task manager will shut down the 5-10 (it varies) Firefox processes.

Tried checking for updates. That also gets stuck trying (let it try for about 10 minutes). Don't see any "reinstall" option.

Tried "Refresh Firefox" (fails....Firefox won't close). Tried "Clear startup Cache)" (same) Tried "Troubleshooting Mode)" (same)

Should I delete it and download again?
