Hi, everybody. I have a problem that I can't solve on my own. In the FAQ or search, I did not find a mention (I could search poorly)

I will try to summarize the essence: immediately after installing Firefox (from www.mozilla.org) on ​​my PC, I tried to enable the synchronization in order to (including) download my extensions that I used previously on other devices. After that, I found that none of them could be installed (they did not even appear in the Add-ons Manager list). In addition, I noticed that the list of recommended add-ons from the Manager's is displayed incorrectly (there are no preview images). When I tried to download a add-on manually from the list by clicking the "+ Add to Firefox" button, I received a pop-up message that "The add-on could not be downloaded of a connection failure" (I use a wired connection (Ethernet) to my PC, without any restrictions. At this point, I was using Chrome in parallel without any problems). I tried to go to (addons.mozilla.org) and found the same behavior. Images were not displayed and extensions were not downloaded (Download failed. Please check your connection.).

What I tried to do to solve the problem: reset the default settings; disable syncing; run in Safe Mode; delete Firefox entirely, and install it again. But all these actions did not solve my problem.

I will be grateful to anyone who can answer me. I'm counting on you.

I use the tree style tabs addon, so I prefer to hide the tabs along the top of the firefox window. For over a year I've used this userChrome.css file to hide them: https://github.com/eriknelson/dotfiles/blob/master/firefox/userChrome.css

Suddenly across all of my machines this has stopped working, and the tabs are still shown. I normally install it by navigating to the troubleshooting information to get my user profile location (ex: /home/ernelson/.mozilla/firefox/<profile>), creating a "chrome" directory, and copy the file there.

Has something changed with the API that would cause this sheet to be ignored? How can I troubleshoot this?

I just download Firefox 72.0.1 (64-bit) on a new computer. It automatically included ublock origin 1.24.2 There are many sites where you actually want pop ups (bank statements, downloads, etc.) On my other computers with Firefox, ublock shows a bar at the top of the browser and gives me the option to say- No pop up, allow once only, or always allow for this site. I didn't have to change any settings to have this happen. However, on this newly downloaded version it doesn't do that and it's very frustrating and cumbersome to use. Basically, I have to know that the site wants to pop up a new screen, turn off ublock, and then remember to turn it back on. I have looked all through the ublock and firefox settings to figure out how to do this and can't see where to make this bar show. Very frustrating! Any tips for fixing this? Or, other, better pop up blockers to use?

My PC is used by me and another person and we use vastly different zoom levels. My partner uses about 0.75 and I use 1.25 in Chrome and would like to set similar zoom levels in Firefox. As I use the PC most and I want the default zoom level to be 1.25. I would like to replace the FF level of 1.2 with 1.25 and delete some of the lower zoom levels. A setting of 0.33, 0,5, 0.75., 1.00 and 1.25 to replace the settings up to and including 1.33 would be my desire. I wish to leave the higher zoom levels unchanged.

I understand I can change this in about:config but would like some assistance in doing this.

Update to FF72.01 Running userChrome to keep Tabs on bottom

1...Tabs appear larger and the text for the titles is sitting below the page 2...Close Tab X appears right after any text, 3...if Multiple tabs open, Close Tab X doesn't appear on some Tabs as well as Titles

Should be a quick fix right?, with the amount of people wanting tabs on bottom, a simple check box should be made available to do this, if the user wants

I adjusted the userChrome.css as per some of the answers posed to similar questions, but no change present

Hi, I hope you're having a wonderful day, and I hope someone can help me with this.

3 days ago, I accidentally press a hotkey, then the web page becomes smaller, and has empty space around it (screenshot: https://ibb.co/RQ74q3Z ). I attached the screenshot below, too. This doesn't affect other web pages. When I open the same page from my other computer, it happens the same way. I tried [ctrl +] and [ctrl -], but it only changes the font size and doesn't make the space go away.

Thank you for your help.

Hi, I really love everything about Firefox Developer Edition, except the JSON viewer. I'm used to looking at plain formatted JSON like the JSON Formatter plugin provide. But, even thought I have installed JSON Formatter (https://addons.mozilla.org/en-US/firefox/addon/json-formatter/?src=recommended), it only shows this tree/table-ish viewer that comes with Firefox Developer Edition. Is there any way to disable this feature and use a plugin for this, just as in Firefox ?

Compact density without changing the address bar text size

After dragging my feet for literal years, I've finally updated Firefox past version 57. I'm gradually working out the kinks and getting things looking the way I want, but one thing I can't get to work how I'd like is the address bar.

Setting the density to "compact" fixed a good majority of size issues for buttons and my bookmarks toolbar, but it shrunk the text in the address and search bars to be much smaller than the rest of the text on bookmarks, tabs, etc.

How do I manually adjust this? Before anyone asks, yes I have a userChrome file, I just need to know what to insert to get this working how I want.

I'm trying to automate a part of my daily work on a website I'm using (not developping). I have to crawl several lists on the website, dig an item in the list, to check some values, and do it again and again ...

Im used to developping in Powershell and python, not with a web browser. I have admin rights on the machine I'm working on. I'd like to use this to catch the json answers of the website (all of them), parse the answers for some values, and automate some kind of popup "Hey, This item in the list is between 90 and 100 !"

No code to show yet, that's what i'm looking for : basic solution for json interception while i'm crawling. I have good knowledge of json parsing using python/powershell, the hard part for me is catching the answers ...

A real time export of all json answers of the network console will be a perfect basis for this ... How can this be done with firefox extension ? I just need a base to start.

Thank you very much for any help you can give. And apologies for my average english ...
