Firefox Support Forum

Firefox is wreaking havoc with my 2018 MacBook Air. It seems to have been invaded by gremlins that are eating RAM and slowing down the works, sometimes causing my laptop to shut down.

I want to delete Firefox and reinstall, but first I want to save all of my cookies and other settings. (I've already downloaded my bookmarks.)

How do I save my cookies and other settings?

thanks very much. Sandy

I'm using Firefox on a Mac with the built-in screen reader Voice Over. When I need to log in to a web page, with a User Name & password stored in Apple's Key Chain utility, I typically press Command-Shift-A & the User name & Password fields are automatically populated. Unfortunately, with my new installation of Firefox, I've found that the key combination in question is used to launch the "Add Ons" window. Is there a work-around for this? The Command-Shift-A is the only way that a blind user can populate those fields from Key Chain. The buttons, usually visible in or around those fields for a sighted user are inaccessible.

Thanks so much,

CJ

I am a biomedical research and need to log into the login.gov site to manage my grants. However, access to this site is blocked in Firefox but works fine on Chrome. I'd rather stay with Firefox but will switch to Chrome if this can't be fixed. Thanks, Claire

OK, I'm not a techie, so forgive my lack of accurate vernacular here, but I was a happy-go-lucky Mozilla supporter and user on all my Apple devices up until recently. I have no idea if there's a causal relationship here, but the serendipity seems to be something worth mentioning.

I signed up for the Mozilla VPN offering in October of 2022. I did not work well enough, and again, I'm a novice at such things, but I stopped using it within a week. Around the end of December, the Firefox browser has had serious problems where it would constantly crash on just about every page, sometimes multiple times. After a few days of that, I trashed the version I had and downloaded and installed the newest version just last weekend (01 JAN 2023). That lasted a few days, but now, all of a sudden, it will not open at all. I click the icon, it bobs twice, then nothing happens. The right-click "open" feature did likewise. I trashed that too and I am unwillingly to try again until I hear some feedback on this from subject-matter experts, if possible.

With my phone and iPad things are working just fine, so it must be my 5-year-old iMac that has been updated to version 12.6.2 just yesterday. Any feedback would be greatly appreciated. I was using Ghostery and every other security feature I could find with Firefox, but in this age of Surveillance Capitalism, who knows what works anymore.

Thanks in advance, and wishing you all well in every way, sincerely.

My issue is that whenever I do a fresh opening of the Firefox app on my 14" MacBook Pro, it immediately opens the App Store in the Twilio Authy app. Can anyone explain why this is occurring? Can someone tell me how to eliminate this problem and has it happened to anyone else?

Up until 2 weeks ago, all ESPN+ and ESPN3 content played on my Mac. It no longer does. When clicking on the start button the screen goes to black, the title of the content appears, but no video. Firefox 109.0.1 MacOS 10.12.6 Content plays as expected with Safari

I am unable to get the "Roboform" (password app) start page to load in Firefox. I have the extension installed as far as I can tell but I believe that's where the problem lies, the extension installation. I am able to install the extensions in both Safari and Chrome correctly so the start page loads in the browsers. Thanks in advance for any help.

I am suddenly unable to drag downloaded files from firefox to a folder on my mac. This is a new issue - always worked before. What's the fix? Thanks

HI FIREFOX! Many websites are not readable. I can see these correctly in Safari. I tried getting the latest Firefox updates. It did not fix the issues. Bizarrely, I can paste into another application and read the gobblity gook. So I think it is just a font issue. I really do not want to go back to Safari. Poshmark and Fedex are the two websites I experienced issues with today. Fedex would not interact properly with Firefox but I could find my tracking information on Safari. I have had the problem previously but did not have time to look into it that day. 16" Macbook Max M1 running Monterey

the activity monitor on my mac shows cpu usage at almost 100% when firefox is active. with safari cpu @ about 15% or less. seems to slow the mac considerably. how to fix?

Hi all, I'm having an issue that I've seen mentioned over several years and without a workable solution - I'm at the point of having to transfer all my browser usage to chrome and abandon my beloved firefox. The issue has been 'answered' by advanced users to tell people to 'inspect' which font is the issue then check local systems font book for corrupted/duplicate fonts: however this is not a satisfactory response. Context: see screen shot attached for what the jibberish looks like, and a point in the 'inspect' view that I believe (guessing) is involved. System: Firefox 112.0.2 (64-bit), MacOS 13.3.1 (a) (22E772610a) on Macbook Pro (13-inch, 2020, 2 GHz Quad-Core Intel Core i5). This same websites do not have any issue on the same computer viewed on Chrome or Safari. Nor is there any problem on my iPhone on the iOS firefox browser.

Firstly this is not a user-friendly solution for most people, I'm afraid. Opening the inspect viewer is mindboggling for anyone who doesn't code and even for people who do some programming but not for websites (like me), it isn't exactly self-explanatory. I think I've managing to find examples that indicate 'Roboto' seems to be consistently involved in the display issue. Secondly, the step for 'fixing' the font that is the culprit - my local system indicates that all fonts are valid and there are no duplicates. I haven't installed manually Roboto as I'm uncertain where to 'safely' get the font from and my computer is owned and managed by my workplace - with overly strict administration/security rules so if I f-up a download of something dodgy my IT service will blacklist me and revoke my admin access... ** which would mean I'd be unable to do my job!**. I wondered if perhaps there is some security setting due to that, which stops website from loading the fonts they choose? From previous 'solutions' it said that having Firefox preference set to "allow websites to choose their own fonts..." should mean the websites can load as needed. If indeed I must manually download fonts for each and every instance that Firefox fails to display text legibly that is equivalent to Firefox being unusable. I'm clearly frustrated and it's because I love FIrefox and the ethos behind it all so leaving for Chrome would be very sad indeed! Help and a solution for normal users would be so very much appreciated. Also where can I properly lodge this issue with peeps who fix things? There are issues of this kind going back years and for both Windows and Mac Systems so it's not a one-off problem but a recurring one! Please pretty please, people who do the magic that makes Firefox - fix this issue... Thanks for reading my rant and for any helpful responses. Cheers, Megan

Tabs to not reliably reopen after closing Firefox. The latest occurrence, but not the only one, was after updating macOS 13 on a Mac Mini M1 using current version of FireFox.

I have read multiple help pages and double and triple checked settings. My work around has been to Bookmark All Open Tabs each time I close FireFox or shutdown the Mac - doable but a nuisance.

Suggestions appreciated

The type face on my iMac has gone super small. So small I can barely read it. How to I return the type face for all programs to a readable size?

I am guessing this is a settings issue, but I cannot find a solution. I cannot see the social sharing icons on my website when in Firefox on my Mac. I can see them in Safari. What's the deal?

Thanks,

Theresa
