Hi Team,

In Firefox, the close button is only partially clickable and is not accessible on the right side. However, when I hover over it, a square background appears around the button. Could you please take a look?

Thank you

Hi, after latest update just now, the browsers uses up to 45gb of ram within a few minutes! Not sure what it is, I am on MACOS Sequia Version 15.6.1 (24G90) macbook pro M1

Hi folks My configuration: MacOS Tahoe FF 15.4.0 When I relaunched FF after restarting the Mac, in the Windows menu all the pages from the previous session were listed but none appeared when I tried selecting them. They must be hidden somewhere. I tried several work-arounds. The one that gives a result is by selecting in the View menu the Enter Full Screen item, then try to go back to a normal view which is a pain in the neck. Is there a clean method to make all those windows come back to their normal position and if possible preventing FF from doing this in the first place? TIA Nick

Original FF user here so not a newbie. Run all FF updates on a regular basis. Currently on a MacBk Air circa 2020 running Sonoma 14.7.7 I browse twitter on a regular basis. I run various ad blockers: ABP, Adblocker Ultimate & Privacy Badger. Last month or so I've needed to make some adjustments as maybe the X platform has instituted workarounds or something but suddenly I was seeing ads that looked like someone's post, very deceptive. At one point it was necessary to disable Privacy Badger on twitter/X as there was an interference w what I was seeing. That wasn't that long ago, maybe 2-3 wks? Consequently if I saw an ad I needed to do a "block element" thru Adblocker Ultimate & while it was a bit of a bother that was all fine and good no problem. Again, this was all recent. Tonite was different. An ad appeared and somewhere something got entangled and I had to disable the Adblocker Ultimate. I sent them an email to see what's up. Then I had to disable that on twitter so ads appeared. Next I tried to enable ABP again on twitter to see if maybe since I'd disabled it a couple of wks prior maybe it had been updated and would work ok. This is when things really started to go downhill. It worked but too well - was disabling images from news reports and/or someone's posted video. THEN I noticed my cpu was running a bit loud. I tried to disable/test the ad blockers but my cpu was getting louder so I shut down the twitter website altogether.

That didn't help. I checked the Utility monitor and saw my activity monitor climbing as I heard the fan running louder. SO bizarre! I shut down FF altogether and this calmed down the CPU. Next I opened just a general news site - Al Jazeera - to see what would happen. Within about 2-3 mins the CPU started speeding up again. I closed AlJazeera, and just sat there for a few moments and my cpu calmed down. Opened it again same thing. Began speeding up. That's when I came here to file a report//ask qs because this just doesn't ever happen - literally ever. It is not unusual for me to have both a browser page open w 2-3 windows along w a private window open - maybe mltiple windows there - and NO cpu noise going on. Once more I shut down FF completely before reopening a new window. IF I start browsing a news site - like Al Jazeera, it begins running hot again. Twitter, same thing and now my ad blockers seem to be messed up//not working as well. Right now as I type this I have ABP & AdBlocker Ultimate both highlighted as active; Privacy Badger is showing enabled but no activity, Twitter Video Downloader is just sitting there as is typical unless I need it (it's to download videos off of Twitter, works very well too.) That's all I have for add-ons. Right now in just this window everything is calm and quiet. IF I open a news site tho, or social media, anything w a bit of activity on it everything starts humming louder and louder. I just opened FB for a few moments to see if that creates issues and yes it does w/i maybe 2-3 mins of activity. Also: FF Privacy & Security Settings are on Standard. Not sure what else I can provide but please feel free to ask. I may have left something out. I'm hearing the cpu heat up again so getting ready to just shut things down for the night. Thanks to all who helped build FF - really - and thanks to whoever can help resolve whatever's going on now.

Firefox freezes when I try to sign into YouTube via Google. Becomes totally unresponsive and I have to close browser. It's the only site this happens on. I have cleared the cache and cookies, unchecked "Hardware Acceleration" and other recommendations from other posts. Please talk to me like I'm your Baby Boomer dad.

This morning, I can no longer download (Save) files to my computer, nor check/change settings in Firefox. Tried all troubleshooting steps to no avail.

If I delete and reinstall Firefox, will I lose all my Bookmarks, etc.? Running version 157.0 (aarch64).

Appreciate any help!

First post. Not really a question.

I noticed last week that some pages didn't load, and Activity monitor showing Firefox app using 170-180% which I know is way too high. Forgot to check memory usage.

I rolled back from 154 to 153 by restoring it from backup, and same with the Firefox folder in ~lib/appsupp/, relaunched Firefox and cpu was back to 2-4% cpu with a couple of windows and tabs. I've turned off auto-updates.

On my system, something is wrong with v154.

While running Firefox on MacBookAir with macOS 15.7.2 to browse simple websites I keep getting the below warning message. I may have 2 or 3 other apps open (like Apple Mail, MS-Word, Preview). "Heavy memory usage You're running out of memory and your Mac may become noticeably slower. Consider quitting some applications. Firefox 2,48 GB" So I quit Firefox to re-open again and continue my work. Does somebody has an hint where this message can come from ? Any settings to change on my MAC ? Thanks for helping

Hi guys - I am running Firefox 157.0 (aarch64) on a Macmini M2 pro with 32GB RAM .

I am regularly receiving messages that my default browser, Firefox, is the largest consumer of that RAM. This is what I received this morning shortly before my system shut itself down. I did have many files open but noticed that Firefox is consuming 33GB of my RAM. Is this normal?

Every since I updated my MacBook Pro M1 Max chip to Firefox 142.0.1 (aarch64), Firefox locks up & has to be "Force Quit" & restarted almost every day. Please update the app ASAP so I don't have to convert to Google Chrome. Thank you!

Hello there,

I realized that quite often when I restart Firefox (Developper Edition) and restore my previous session (latest occurence with 46 tabs), the window becomes invisible. It still exists, and I can even see it in the Window menu list pointing to my latest tab but it's nowhere on screen. I can add/navigate through/select/remove tabs using the keyboard, I can see them listed on screen when I Ctrl-Tab but the whole window remains invisible.

It'd be great if someone could help me out.

Best regards,

Emmanuel

I use a Mac running macOS Sequoia 15.7.2. Each time I attempt to login to https://music.amazon.com, Firefox freezes which then requires me to quit Firefox and restart. Therefore, I need to use another browser to access the site. What is the solution to this issue?

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.

Any ideas?

'I am running fiefox version 147.0.3 in MacOS version 26.2. Every second time I start the program firefox tries to take 15GB of memory. The process does not respond (as this is equivalent to more than the memory available plus the swap space). I have to kill the process and the second time the program has standar memory needs. How can I help developers?

I'm elderly,so bear with me. Firefox very often slips off the screen or simply vanishes.Often it disappears to a thin,gray line at the bottom. Can't open a document and have Firefox available,too. I'm 84....are my fingers worn out? Dave P.

Hello team,

I tried searching for a solution for the problem I'm about to describe but unfortunately I wasn't able to move forward.

I am running Firefox 141.0 version on my Macbook M4 Pro. The refresh rate of the display is set to 120Hz, but I the scrolling and interaction in the browser feels like it's on standard 60Hz refresh rate. When I compare it to Safari/Chrome it's not as fluent as it should be.

Am I missing an existing option that could be changed or is it something available at the moment?

Thank you, Arsen

Hi whenever I use my Google account to sign into websites (Google, ebay, YouTube, & anyother sites,) Firefox will become unresponsive, the window containing the tab i was using becomes unresponsive, sort of. - I can't click any open Firefox Tabs, - the red 'Close' radio button is greyed-out, so I can't close any tabs or the window - right-click is unresponsive, so i can't close tabs that way, but Command-W closes the tabs normally, but the others are still unresponsive.

- i can open a new Firefox window (with &/or without Tabs,) which works normally.

- & unrelated, but earlier, Firefox was running really slowly, Youtube videos were slowed down, but audio was normal, and scrolling was slow.

When I launch Firefox in Troubleshoot Mode and try to open the Settings page (about:preferences) right away, Firefox becomes unresponsive. This issue does not occur when Troubleshoot Mode is off.

I'm using Firefox 140.0.4 on macOS Sequoia 15.5.
