Hi,

I cannot download & installed any add-ons or themes. After clicking the install button, I always get a red bar saying "Download failed. Please check your connection.". This happens on Firefox, Firefox beta and Firefox nightly.

I did some googling and found similar posts from a few years ago. These seem to suggest I don't have the correct certificate used to verify extension signatures:

I checked my certificates and I don't have anything from "Mozilla Corporation - signingca1.addons.mozilla.org" (there's a screenshot of this cert in the first forum link above), so I think this is indeed the issue? I've attached a screenshot of my cert list where the Mozilla cert should be.

Please note I am on an M3 Pro macbook pro. It's a work laptop and I thought maybe our network settings were interfering with things, but my previous work laptop (Intel) could install add-ons just fine.

Would appreciate some help!

P.S. I found a workaround where I copied over all extension JSON and XPI files from my old laptop. So I am using my previous extensions just fine but still cannot download any new ones. Also I don't have access to my old laptop anymore so can't copy over any new ones.

I don’t understand what Firefox is doing. For example, I used to start typing the first few letters of “weather.com”, which I visit pretty much daily, and it would auto fill “weather.com”. Now it auto fills every time with http://www.weatherbase.com/. I don’t know where that came from. Similarly, I used to type the first few letters of “duckduckgo.com” and it would bring up “duckduckgo.com”. Now it brings up a magnifying glass below the url with “Search with duckduckgo”. I am thinking it might be best if I can start over, i.e. clear out any information it’s saved about where it thinks I want to go, and start remembering the sites I am entering now.

Hello - I keep searching for various fixes to this, but nothing seems to work. I have the latest version of firefox. Macbook user. Catalina 10.15 I find that with almost any website that I'm trying to log into, or enter a credit card and other information, the browser does not show these items, pull downs, forms to fill in etc. I'll go thru a whole process of something, and will be directed to click a box or some such that just isnt there. So I move over to Safari, and the entire page loads. I've adjusted the privacy, cleared cache etc. It's like I'm on an ancient browser.

Any help welcome.

115.8.0esr (64-bit)

This newest release has a massive memory leak. I know it's Firefox, because I look at the system monitor, and there are even more entries for firefox.com running than usual. The first one on the top of the list is the biggest resource hog, and the next one is second. All the rest have something going on, but smaller. Looking at performance in the Windows Task Manager, under performance, the memory usage goes up. Right now, it's 5.35Gb of 16Gb. At worst, several days ago, it was at 12Gb. When I force close Firefox, the memory and usage goes way, way down, to a usable level.

I wrote last night. "Ed" someone got back to me, didn't quote my message, and said he was from another department. I DID EXACTLY THE SAME THING AS LAST NIGHT. I hit the blue button, which took me here, and he advised me to do today, which brought me here, AGAIN.

If this, again, goes to "restoring access to Mozilla accounts and subscription services such as Mozilla VPN", please be professional and forward it to the right department, possibly with my message quoted, as this is the second time I'm creating it, and only have my memory on which to fall back for the first time. The logical topic is "Fix slowness, crashing, error messages, and other problems".

At the same time, other releases have had big memory leaks, and they seem to get patched quickly.

Thank you again.

Firefox runs fine most of the time. If I right-click to download an image, or click a link to download a PDF or other file, or Save HTML, I see the "Save file" dialog, click Save and then Firefox freezes up for a while, maybe a minute or two. Pages won't scroll. I can't switch tabs. I can bring up a different firefox window and it redraws its contents, but I can't scroll or do anything else.

This didn't happen a month ago, then one day after a system upgrade, it happens every time. I'm using FF 123.0.1 on Arch Linux. 64GB RAM, so it's not a memory shortage. I have upgraded one or two times more since the upgrade when this appeared. Chromium is not affected, Thunderbird is fine, and all other software continues to be fine as before, including when saving files. Only FF has this problem.

What is the problem and solution? Are there ways to gather more info to diagnose the problem, if needed?
