Hello everybody,

There are more and more websites that have functions that no longer work with Firefox and force me to use Chromium instead. Do you if there is any chance that an upcoming release will put everything right?

Thank you in advance Virginie

Hello everyone,

I'm an avid user of Firefox latest on Manjaro, up to date.

Since yesterday, when I updated from Firefox 87.0-1 to 87.0-2, I have a strange bug using DuckduckGo.

What happens ?

  • When on DuckduckGo result page, clicking a link won't open when using the "Open in another tab" setting
  • I will open the link if that setting is not used
  • I can open it in a new tab with the right-click menu, or by ctrl-clicking it.
  • When hovering above a link, the bottom-left tooltip does show up and the cursor does become a hand, suggesting the link should work. Alas, it doesn't.

What did I try ?

  • I did restart in "safe mode", with all addons disabled.
  • I did reset the cache.
  • I tried testing the same behavior on Google, and it did work as expected.
  • I tried DDG in another browser (Gnome Web/Epiphany), and it worked as expected.

I have yet to notice the same issue with any other website. Any Idea where I should report this minor, but annoying but ?

Thanks & Cheers, -- JAB

Hi i would like to know how i can change the font size of my Firefox Menu.

i already change the size of the layout whit "layout.css.devPixelsPerPx" but it didn´t change the font size of the tabs or the menu. i did some research and found the userCrome.css technique to change some fonts sizes. i already change the font size of the address bar, PopMenu and tabs. But when it comes to the Main Menu, and bookmarks the font still in the same size. i also try changing the fonts size on preferences but nothing has been working.

i guess there must be a simple command line to add in the userCrome.css file to fix this but i can find it.

if some of you can help me i will appreciate very much.

i am working on a linux machine. thank you very much

I have reinstalled the OS on my lap top and after a successful login to my account I am unable to sync everything from the account. The logs can be found in: https://controlc.com/8afabe84

I have the same account set on two different devices (My desktop PC and my android phone, this device I am trying to sync is the third one) and both those device were synced long time ago.

I tried with another profile which I am using for my work related stuff, still no success. First I tried syncing on Ubuntu 20.10 and then installed on Ubuntu 20.04(currently) but it is without success.

I need to sync to this device the bookmarks, extensions, saved logins, etc... Currently I do not have my other PC to export this stuff, please help.

Some of the thing in the logs:

Hello, the problem with Firefox is that it loads the pages too slow, other browsers such as Chrome or Opera are working correctly. At first everything was fine but suddenly Firefox started to take forever to load the pages. I have completely uninstalled Firefox and installed it again but the problem persists. I thought it was a problem with some extension (I only use AdBlocker and HttpsEverywhere) but restarting it in safe mode the problem persists. I also have to mention that the Ubuntu installation is recent. What could be the problem?. I am using Ubuntu 18.04.5 LTS.

I'm working on an addon to automate taking screenshots of lecture slides. I'm using a canvas object to capture and save the file blobs and JSZip to zip everything together and download. But JSZip keeps throuhing the `unsupported file type` error. Even though blobs are supported.

Here's the relevant code I'm using Github File

I've submitted an issue to the maintainer which has some more debugging info. The script in the addon_context has some very quantum behaviour and changes output every time I console.log Github Issue

I'm wondering if there might be a problem on my end, with the way I'm generating and processing the blobs. The same code works in chromium based browser, I'm confused as to what Firefox does differently. Any help would be appreciated.

FF profile choice problem on Linux Mint with Claws email

I have three FF profiles on my Linux Mint 19.3 system (work, not-work and one for e-tail). Somehow the problem only appeared after I added that last one. All profiles have the same syntax; I checked the files. Neither one is set to be the dominant one. Typically, I don't use more than one at a time.

I also use Claws mail. Whenever I get any mail with a link I want to check out, I just used to click on that link and it opened in a new tab in the FF browser profile that was currently open. Similarly, whenever I wanted to see the HTML version of a mail, I right-clicked on the html-icon and chose open. Again, it picked the open browser.

Now, though, whenever I pick either one of those options above, I get the "Choose User Profile" box. If I pick the profile that is currently open, I get an error telling me that it's already running.

Since I mostly read email when I use the no-work FF profile, I tried to add "firefox -P NotWork -no-remote --class NotWorkProfile" but that also resulted in the choose user profile box to open.

My current work-around is to copy the link and open it in a new tab, or pull the whole mail into the tab to see the HTML version. Quite annoying.

Is there any way to get it to ignore all other profiles but the currently open one? Thank you for anyone who has an idea. Let me know if there's anything else I may add to explain the situation.

[My apologies if this isn't the right forum; I'm also attempting to ask this question in the Linux Mint and Claws forums, if those exist.]

Hi! Glad someone is here to help!

Last week I was signed out of my Hotmail account. Which is now technically Outlook, but I still have a Hotmail email address. I did not sign out. Just came home to discover that I was signed out. I found the main Outlook sign up page, which also had "sign in" on it, which I clicked.

The next thing that showed up was a mostly blank page with the Microsoft squares, my email address, and password filled in in the upper left corner of the page. Underneath it said "next" which I clicked, and nothing happened. I tried to chat with Microsoft about it, and in the end I downloaded Chrome, which instantly let me into my account. I truly don't want to use Chrome. But so far my ability to access my account via Firefox has not been successful. I would be so happy if anyone could help me understand what is gong on, and how to fix it. Thank for reading this!!!!!! ps I have Linux as my operating system. I had someone who knows Linux well come to help me, but he couldn't figure it out either.

I am attempting to change my secondary email address with the intent to make my new email the primary email. I have removed the old secondary email, but when I try to add the email address that I want. I get an error message saying that the email already exists. I note that in the Firefox account dialog the secondary email address is blank.

I did sign up for Firefox VPN using the email address that I'd like to use and so that's a possible reason. I just don't know how to fix it. Note; I'm no longer planning to use Firefox VPN. I wonder if perhaps there's a way to cancel/delete that account.

Hello,

I used my firefox account to restore my browsing history after I switched to a new hard drive. I compared the contents of places.sqlite from before and after the switch. (I can do this because I made a backup of the old places.sqlite.) And I noticed that many entries of moz_historyvisits are missing in the new database. I made a graph about this, in which I am using pythons sqlite3 library to inspect the databases moz_historyvisits.visit_date column. For every visit_date I checked if it is still present in the new database or if it got lost. The pattern seems highly irregular.

Does firefox intend to maintain a complete history? By which criteria did individual history entries get lost? Is there a way to restore a complete version of my browser history from my account?

Any help is appreciated.

Clicking "Show more comments" on Facebook does nothing (I browse it without an account), also no comments are shown in Cracked.com, I haven't noticed if other sites don't show comments. I use Ubuntu 20.04 (when I first opened FF on this pc it had the gnome icon and I hadn't checked for this problem before importing my old profile with add-ons, now it doesn't show the icon for some reason), I tried safe mode, refresh firefox, creating new profile, uninstalling and deleting home/.mozilla folder, no luck. Before I got this pc I used my old laptop with windows 7 and I'm pretty sure I had the same problem with facebook comments that had started some time earlier.

I believe everyone has a right to choose the browser and operating system they use. I choose to use Firefox because I care about my privacy, and because of features like multi-account containers - as a software developer these are non-negotiable. I choose to use Linux for similar reasons, and many Linux distributions come with Firefox preinstalled as a default browser. In light of recent changes to Google's data collection through Chrome, I am more than ever committed to using Firefox as my only browser.

However over the last year or so, I have noticed an increasing number of websites or features on websites have stopped working in Firefox on Linux, forcing me to use Chrome against my wishes. Examples include the entirety of the Australian government's MyGov website; the phone call feature in Slack; and Google Meet meetings (no audio). I know people who use Firefox on other operating systems and they have not had these problems, so I can only assume that the issue is specific to Firefox on Linux.

I am not trying to suggest that Mozilla is responsible for this in any way - if Google or Slack or the government refuse to support Firefox on Linux, that's their responsibility, not Mozilla's. However, I am not convinced that the lack of support is intentional, or that it isn't a quirk of the particular Linux distribution I use or the version of Firefox included in the package manager. Any advice would be appreciated.

My Firefox version is 84.0.1, and my Linux distribution is KDE Neon User Edition 5.21 which uses Ubuntu 20.04 under the hood.

According to https://www.reddit.com/r/firefox/comments/8k3sq4/firefox_updated_to_6001_and_the_search_box_is_no/ there's something wrong with userchrome.css in the profile but that file should be patched if that's the case.

Why this hasn't been patched since it's introduction in version 60 is beyond me.
