I'm on an older iMac using OS 10.10.5 Yosemite. I can't upgrade due to work.

Currently I'm running Firefox 78.3.1esr (64bit) and I'm having trouble seeing some websites correctly (see attached screenshot for ebay for example). Sites also take a longer time than usual to render.

Is there anything I can do to make Firefox work well again?

Thanks!

Please Help! Why am I all of a sudden getting this error message? I have been using Firefox for years and Gmail.

Do you really want to use HTML Gmail?

You're about to use a version of Gmail designed for slower connections and legacy browsers. To get all of Gmail's features, including inbox categories, images and quick actions, please use the latest version of Gmail (recommended).

Take me to latest Gmail

I have disabled autoplay in my preferences for all websites, but some videos on some websites still autoplay. (This is under Preferences / Privacy and Security / Autoplay. Under "Default for all Websites", it is set to Block Audio and Video.) How is it that some websites are able to get around this? Is there a way to defeat them?

I am unable to clear cache. 2.0MB of cache always remain after I go through the appropriate steps to clear cache. I have tried everything recommended by Mozilla and online. A few times the 2.0MB cleared on its own but then immediately reappeared. This problem started happening around six weeks ago. I checked the cache folder and nothing appears there but when Firefox is open it always shows 2.0MB of cache and it won't clear.

This past week I started getting the Did Not Connect: Potential Security Issue warning when I tried to access my email at Comcast.net. I also got the warning on my banks website when I tried to transfer funds, something I had done many times before. This seems to have started after "upgrading" to version 78.7.1 of FireFox. However, I got the same sort of error using Safari: "Safari can't verify the identity of the website xfinityconnect.email.comcast.net" The certificate shows it is issued by "AVG untrusted CA" from the country "CZ" and State/Province "Brno". Comcast told me to just trust their certificate and I was able to get to my email account, but I am getting the same warning from PNC Bank's website when I try to transfer funds. This REALLY has me worried. Can someone tell me if this is a sign I've been hacked? How can I fix this so I can again transfer funds from my checking account to other banks?

Is there any way to temporarily disable Firefox (and Thunderbird) update reminders? Mozilla seems to be updating its software so often that I'm getting too many reminders and it's interfering with my work flow. I understand the need to keep software up to date as often as possible but this has now got ridiculous, and I am on the verge of changing my default browser from Firefox to Safari, Chrome or Vivaldi. Please stop forcing every little tiny update onto your users!

Or is there some sneaky little way I haven't noticed under Preferences which already does enable me to do this?

Fonts Not Displaying on Some But Not All Sites

My desktop Mac suddenly (July 28) quit displaying page specified fonts, in some - not all - instances, using Inspector reveals affected sites defaulting to Helvetica Last Resort, or failing to display Open Sans via gstatic.com. For comparison, my laptop - same FF v.78.12.0esr, using the same (advanced - default) fonts and colors settings - displays everything properly, as do those same sites on mobile. This is a local problem.

Those sites affected work fine using Chrome, Safari, which indicates system level fonts are loading properly.

Of the sites affected, one thing in common seems to be that they are WordPress/PHP dynamic sites.

I use FontExplorerX font management, which has been stable for years. There aren't any reported conflicts.

Application and system font caches have been flushed.

Firefox has been freshened.

I feel like this may be a corrupted prefs file somewhere, but have no idea how to proceed.

Attached images show different page display results using same search term in Google, DuckDuckGo, and two sites that are affected.

New versions of Firefox are very slow for download speeds. 50% of what is available from my provider. Safari is at 100%. Is this from security and filters ?

Recently updated to the latest 2 versions and Firefox is failing download speed wise. Upload speeds are what they should be. I have ran speed tests from multiple sources and all return a similar range - 40-60Mbps. My provider speed is 100Mbps. I have run the same tests with Safari and it is operating at 100% speed wise. Are new security features and / or tracking filters responsible for this slow down ?

I do banking online with Key Bank and now they are saying: Due to security concerns, Firefox is no longer an option for KeyBank online banking. Nothing is wrong with your account. You simply need a different browser—like Microsoft Edge, Google Chrome, or Mozilla Firefox—to sign on to online banking.

What is the difference between Firefox and Mozilla Firefox? What do I need to do?

FireFox just updated onto my older Mac computer running OS 10.10.5 to version 78.7.1esr. I now cannot login to at least one of my banking and medicare accounts, but can log into other accounts I have. For the banking account I get this message: "Please try using another internet browser. If you still receive this message, please call the Customer Care Center at 1-800-XXX-XXXX and reference code: 18.67472317.1612970980". For Medicare I get: 'Access Denied You don't have permission to access "http://account.mymedicare.gov/?" on this server. Reference #18.47f86668.1612971914.68502162'. Using Safari I can login to these accounts just fine. Turning off all extensions does not remedy the problem.

I have a another Mac, running OS 10.12.6 and Firefox 82.0.3 and I don't have problems logging into these accounts.

For about a month I'm unable to log into my Yahoo Mail account from Firefox on my Mac. All the proper screens appear and I fill them in, but when I hit "login" Firefox hangs. I see the circle thingy rotating indefinitely.

I know this is a Firefox issue because I can access my mail from another browser (e.g. Safari). I think it also relates specifically to Macs because I've never had this issue on my PC.

Firefox is the latest version (78.2.0esr (64-bit)). The Mac is a Mac Pro Mid-2012 running Yosemite 10.10.5.

Thank you!

Hi there

New Mac Book Pro M1 running Big Sur 11.1

Firefox is being a nightmare. Forgets everything. Logs out of everything. Logs out of Firefox itself everytime I quit. So everytime i open firefox I have to sign in to Google (my homepage), BUT... because it has also logged me out of Firefox itself, I have to enter a very long password each time. Sooooo boring.

What is going on? Is this really apple not wanting people to use anything other than safari?

Any help gratefully received
