Suddenly when I try to go on Youtube, I get messages that I'm blocking ads. I'm on a Mac-mini using X El Capitan V10.11.6, which is the highest I can upgrade to. I'm using Firefox Browser 78.15 (64-bit) and info shows it's up to date. My old Safari browser still will work with Youtube, but Foxfire is my go-to browser.

I had installed FF version 78 ESR in a newly formatted SSD back in 2020. At that time, two profiles were created automatically under the Profiles folder: xxxxxxx.default, and xxxxxxx.default-esr. The first profile, the one without the "esr" suffix was never used - I don't even know how to switch into it.

The non-esr profile folder had always contained only 6 files totaling about 70 KB. The contents never changed - until a few days ago.

A few days ago I noticed the non-esr profile folder was modified. It now contains 28 files totaling 125 MB. 26 of the 28 files were modified on the same day (May 23rd), at 2 different time points. That folder and contents haven't changed since then.

I continue to use FF using the esr profile without apparent problems, but I would really like to know how/why the non-esr profile got modified suddenly. Any ideas, anybody?

Hi there, Please see attached image of screenshots of searches on Firefox and Chrome. The Firefox search images are incomplete whereas the Chrome images are complete. This has only started happening on Firefox recently. Can you please help me resolve this issue. I have cleared the cache & cookies, restarted my macbook etc but nothing has worked. Thanks in advance, Paul

been spending the day updating passwords and i finally had to update my firefox account password, sadly i had lost the original password so i had to fully reset it. Idk if that contributed to the issue at all but ill mention it just in case this is a known problem. now im trying to sign back in and it just keeps getting stuck loading saying "working" some other things, I use waterfox as my laptop runs macOS 10.11.16, so I'm also worried that this is not a bug but a "feature" intended to push users to update their browsers. as i type this its been "working" on signing me in for about 5 minutes and i doubt its doing anything but spinning that wheel around for show. i was able to sign back in on my phone, any help?

I have the latest version of Firefox 78.15.0esr (64-bit) on my Macbook Pro. Netflix says, "Looks like your browser is no longer supported. Please install the latest version or install another browser. Error Code F7121-3078" (see image 1).

Netflix streaming works fine on Opera, but I can't get it working on Firefox, even though it was working fine on Firefox a couple of days ago (Sept 15, 2022). Any help you can offer would be appreciated very much. I have two plug ins: Facebook Container and EFF Privacy Badger. There is no update available to update Firefox. It appears that when the new version of Widevine updated yesterday (see image 2), the browser stopped working for streaming on Netflix. Widevine version 4.10.2209.1 (updated Sept 16, 2022).

Two questions regarding FireFox ESR for legacy macOS:

Is there any plan to make Yelp compatible with FireFox ESR? It hasn't worked correctly for a couple of years…

With the conversion from Intel to Apple Silicone macs, any idea how much longer will FireFox ESR support the Intel platform?

I accidentally deleted the blue star on one of my book-marked items and am struggling to get it back. Its very useful so i can see immediately if somethings already been bookmarked. Plus I could remove easily and/or put into other folders. All solutions appear to be to go to customize firefox and to drag and drop in some bar at the top of the page BUT when i do this it STILL doesn't come back. HELP!!! (Please explain in total laymens terms and don't nauseate me with technolingo.)

The top informational header for my Earthlink email has vanished on Firefox. I still receive email but cannot reply/forward via Firefox. a complete and correct Earthlink email is still found on internet and their website.

How do I get the header for my email back on Firefox?

Thank you.

Have many many bookmarks saved

Thank You

I just "discovered" the existence of ESR, as 78.15 on my wife's beloved 2009 Mac OS 10.11. Our newer Mac is ok with OS 12.6 and Firefox 110, auto updating. We dislike relentless whiz-bang changes, and need just email, simple games, and basic browsing on the older Mac; email, moderate browsing, flight simulation, and some streaming on the newer. In plain English, please, what are pro and con of switching it to ESR?

For the past several weeks when I click on Messenger from the Facebook web page I get a blank page with the Facebook header. Same if I click the little shortcut button (brings up a blank box). I've cleared all cookies and cache but no change. I do not have this problem with Safari so I believe it is a Firefox issue and not a Facebook issue.

Some webpages, that I must log in to, are coming up blank, when I attempt to login. No error, just blank white page. Two examples are paypal and textfree. I have cleared everything I can think of or find on the internet. I have refreshed and restarted several times. This has all started int he last few weeks. The two sites mentioned are ones I really need access to. I am not sure if it is my machine or the browser.

Hi All,

I'm using an iMac with OS X El Capitan 10.11.6. I am using Firefox 78.15. When I click on links, nothing happens. I have to right click and select "open link in new tab." I suspected it might be an out-of-date Add-On. So, I disabled all add-ons and restarted Firefox. It had no effect.

This problem is getting annoying Any assistance is greatly appreciated.
