Firefox Support Forum

mailchimp.com website overloads CPU and hard drive usage in Firefox (Windows and Linux desktop versions), preferably after about 1 hour of work with website or after logout from account, issue is absent in other web browsers.

firefox is my default browser, but if i try to open a link via Mail on my Macbook Pro 13" 2012, it always opens in Safari or any another browser i have installed on my MacBook. Can anyone explain how i can get them to open in firefox?

I have some problematic settings that are continually syncing back to devices when signing in - I would like to understand how to wipe all my data from the sync servers to essentially start fresh and push new data to the server from one device to then sync this to my other devices using Firefox.

Is it possible to remove ALL data synced from Firefox to the sync server?

Hi, Since this morning, for some unknown reason, when I place my cursor over a text section in my browser, one or two seconds later a rectangle appears below with the same text inside (it does so with ALMOST all text, regardless of the fact that it is or isn't clickable, apparently, but it does not work with some text here and there – for instance on this very page). It does not correspond to anything I've (voluntarily) asked for, I haven't found anything in the FF settings that relates to this, and I do not think it has anything to do with the plugins I use, though it does correspond to my installing this add-on this morning: https://addons.mozilla.org/en-US/firefox/addon/new-tab-suspender/. Which I've temporarily deactivated... but the popup rectangles keep appearing. Does anyone know why these popups have started appearing all of a sudden, and can anyone help me figure out how to get rid of them? Thanks in advance. Best, jpg

Firefox: latest (86.0 at the moment of posting this question) OS: Ubuntu 18.04.5

Problem: Firefox always reports time (to sites) in UTC (my correct timezone is UTC+7). That refers to site like everytimezone.com.

At the same time, Google Chrome on the same system reports correct time.

System clocks are synced to external time servers, time drift is negligible (if any).

How can one make Firefox report correct time (preferably without any extensions)?

I made changes to my about:config that improve the privacy of my browser, but I realized that I want to keep the default settings in firefox developer edition as I do web development. Is there a way to export the about:config settings that I have modified to the normal version of firefox so that I can use it for personal stuff?

Firefox has an option where you can see and copy saved passwords. is there any chance that i can block this or hide it. just a way that i can prevent people from seeing my saved passwords. thank you.

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

Firefox updated on my work machine concurrent to a machine self-restart and VPN update. The VPN update bricked my access to shared drives for my work network so I assumed the issue lie somewhere with lack of internet access and inability to connect to said network. Now the VPN is up and running with normal file access restored, but all my FireFox info is gone. I see on my desktop a file called Old FireFox data and begin googling the recovery process. I generated a new profile in FireFox and copied over all files from the old profile to the new including key4.db and logins.json to no avail.

There are no passwords, no login info, no cookies, no bookmarks, nothing is left. Also, I cannot copy any of these files. I can only move them for some reason. I've tried to back up these files, but they are move-only somehow.

Any advice?

hi,

I have a new install of firefox (78.7.1esr) on a new Apple Mac (10.15.7 Catalina). I used sync to sync bookmarks from an ubuntu install (85.0.1) onto the Mac.

The bookmarks arrived. They are visible on the bookmarks toolbar, bookmarks menu, and bookmarks / show all bookmarks. I can add new bookmarks using drag and drop, or by the bookmarks menu options. These bookmarks can be seen in the Bookmarks / Show All Bookmarks menu. But they do not appear in the bookmarks toolbar. It's as if there are 2 sets both started from the same sync.

• Bookmarks added by drag and drop visible through the toolbar
• Those added with add bookmark or show all bookmarks within the toolbar folder do not appear on the toolbar.

I've now got what looks like 2 sets that are drifting out of sync on the same latptop.

thanks for any help.

My Firefox browser quits unexpectedly several times a week. When I reopen it, I do a session restore and everything works fine. What makes this happen over and over?

The mozilla firefox stop working suddenly on Windows 10, i tried almost everything and i was not being able to fix it. What i did is :

1. Started firefox in safe mode 2. Uninstalled compeletely firefox and then tried to install it, on end of installation was getting the error the application was unable to start correctly (0xc000000d) 3. checked about:crashes is not possible because only allow you to write and nothing else happens if you press enter stays as it is

Somehow firefox installed and i am only able to start it on compatible mode, how can i fix the problem and see what it happens?

Running in compatible mode breaks the visual on full screen also.

I have cleared all of my history multiple times, and still, when I search something on my Address bar, earlier sites show up. This is especially annoying, as I had cleared my whole history a while ago, so it doesn't take up as much space. Earlier, when I wanted to go on Google (My default search engine is Duck Duck Go, but sometimes i need Google because Duck Duck Go doesn't show what I want), I'd just have to type "g" and press enter. Now when I press "g", it shows "gamingjs.com". How can I get rid of this Website?

Also, even if I type "google", the first suggestion is still "google - Search with DuckDuckGo".

I can't provide a screenshot, as the address bar collapses automatically when I make a screenshot.
