Firefox Support Forum

Obviously people have asked this before, but those threads all seem to be closed now. The idea that a browser would not want to have a consistent UI with every other part of the operating system is absolutely nuts, so why is it not easier (or even automatic?!) to place the 'close tab' button on the left when running on a Mac operating system?

I have tried the solutions recommended here – https://support.mozilla.org/en-US/questions/1253751 – but without any success. Maybe someone could help me understand what I am doing wrong? Better yet, maybe Mozilla could remove the need for such workarounds and implement what ought to be a standard feature?

I have tried all of the about:config options to disable the auto-reload of the tabs. I have this working fine on my old machine macbook pro 2015 (same firefox version), but on the macbook pro 2019 i cannot get it to stop. Any help would be great as I need to switch between tabs during meetings and dont want them to keep relaoding

When I first go to the URL bar to either search or enter a URL I see a drop down of sites. These are not the search engines. See the image attached. How do I remove these?

Firefox version: 95.0.2 (64-bit) OS: macOS 10.15.7

Any way to force all HTML files to open in a new tab rather than a new window? This really could be annoying when you are working on several local HTML files at once :(

Hi, Firefox brings my computer to halt after a few minutes of usage. The only thing I did after opening the browser is go to support page and the FirefoxCP WebExtensions process memory usage went over 20 GB of memory.

I have tried restarting my MacBook a few times as well as restarting firefox, but nothing has helped. I’ve the latest version of FireFox installed, and using a MacBook Pro with 16GB of memory.

I haven't made any changes nor added anything new lately. I think it may have started after the last update.

Thank you for your time and support!

Now, in the old Firefox, you used to be able to select "Email Link" to send a URL to someone by e-mail in your favorite e-mail client. I used to do that routinely, sending links via Thunderbird. I'm now using FF93.0, and all I see is "Share", which, when you point it to "Mail" it dumps you in Chrome. Now, in my FF prefs, I have specified Content Type->mailto->Use Thunderbird, so why it's dumping me in Chrome makes no sense.

How do I use Firefox to share a URL in Thunderbird like I used to be able to do?

Hi, for the past week whenever I open Firefox (FF) it works normally for about two minutes, then slows, then causes my entire mac to slow and freeze. If I don't force quit FF quickly, my mac crashes. Once I force quit FF everything is fine. I've been using Chrome for the past week or so hoping FF would fix itself with an update but no go.

Anyone else having this issues?

I cannot set my preferences because the preferences menu will not display when I select Command, from the pulldown menu under Firefox in the top left banner. I am stuck with whatever this is. I cannot set my search engine. I cannot set my popup preference. I cannot set any preference. I use Mac BigSur 11.5.2. I can't share data. I am having trouble streaming my favorite radio station because I cannot reset my popup preference for the station. Nor can I use my search engine: DuckDuckGo without typing it into the Start search box because I cannot set my search engine preference. I cannot set other preferences because it seems I don't have any options since I can't get the preference menu.

Firefox RAM usage on M1 Mac has dramatically increased. Unfortunately, b/c the memory usage is in firefox parent process, I can't simply terminate a process corresponding to a "tab", meaning I have no choice but to restart Firefox (closing & reopening all tabs) every hour or so of usage.

This is a new issue from a long-time firefox user (on multiple operating systems). It happened after I upgraded the Mac to "Monterey", which may or may not be coincidence.

Certain emojis are no longer showing up for me while using Firefox. They will show up as as little boxes with numbers and letters instead of the actual emoji art. This doesn't happen with all of them, only certain ones. I have attached a few screenshots for reference.

Also, I have attempted to fix this issue by changing my default fonts, disabling addons, etc. Nothing seems to work. When I use Chrome, I have no issues seeing these emojis.

Thanks!

Hi everyone,

I have the problem in the Subject line. FF sucks about 500 MB to be run, on top of which it takes 500 MB per tab, and that makes it impossible to run a research on my 8 GB Mac. Yesterday I was looking for a lamp and had no more than 7 tabs open, 3 of which were largely text, 2 were online shops, and 1-2 were websites with pictures. No Facebook or social media, no YouTube. FF froze, made the whole Mac freeze (well, Mac is garbage nowadays but let's leave that out of this topic), and I had to wait MINUTES before I could close it, because the computer was nonreactive.

When I check online, I see people being like "why can't it manage more than 50 tabs?". 50?!?! My computer dies with a maximum of 10 when it's only text websites!

So, I guess there's something wrong with this.

- I don't have many extensions (SimilarWeb, VPN, and Flash Player), I always use incognito so I can't use the plugin that allows me to use several accounts at the same time, so I can't see what's messing with my Mac. - The Activity Monitor (pretty much Task Manager on Windows) shows "FirefoxCP Isolated Web Content" for each tab, could that have anything to do with my problem? - CPU usage is very low, some 0.5 to 10% max during heavy use. - I seem to remember I used to have dozens of tabs open in the past, although I can't be sure. Is this a recent problem?

I really hope there's a way to solve this, because now I always fear that opening FF while on a Zoom meeting might freeze the whole thing.

Thanks to anyone who might want to shed some light on this big problem.

Screenshots: RAM and CPU usage with 2 tabs open. Two, taking more than 1 GB of RAM and about 250 threads in total? While using 0.2% of the CPU? I'm lost

I've got a new computer I am setting up from scratch, and though I have set FF to sync settings, I'm still having to customize a lot. My bookmarks toolbar is crowded again with icons and I'd like those to go away. I don't mind other icons staying around on the tabs--that does help me navigate faster. I had this set up before, but lost the setting when I refreshed Firefox.

Whenever I go to Amazon.com the site displays in a micro format (about 20% of the screen in the center), too small to read at all. Yet if I use Internet Explorer I do not have these issues. I have cleared my cache etc (no luck) How do I fix it.

I use Firefox quite a bit and installed it on my wife’s MacBook air and I’m trying to get her to use it. I recently set up a gmail account for my brother-in-law who does not have Internet and uses my wife’s MacBook air when he visits us. 

A couple of days ago the mystery icon—Firefox logo with a tv screen on the upper right—started appearing on my MacBook pro every time she turned on her computer. There does not seem to be a way to get rid of it. Any suggestions?

FF is offering me two versions of my e-mail when I login to a website where I have specifically told it to 'never' remember a password. The little black selection dropdown shows both myUserName@myMailserver.com myUserName@myMailserver.co When I click to login page of 'website.com'. It does not offer this for all websites that use e-mail address as login.

I have checked and the website in question shows up in 'never save' exceptions to my 'ask to save usernames and passwords'.

So I have no saved passwords to remove for that site--when I look up 'website.com', I get nothing.

2 questions: why does FF continue to offer a login name for that site?

FF 93.04 beta (will be updated in a few minutes to next version) MacOS 11.6 Big Sur and where can I find and zap 'myUserName@myMailserver.co' without losing all of my other logins & passwords that I do allow FF to store for me?

When I'm using the Firefox browser a small pop-up box often appears saying "Must provide password." If I type in my actual password and hit Enter, the box just pops up again. If I hit the Cancel button it goes away and doesn't seem to affect my use of the browser. Is there a way to get it to stop popping up?
