Today I updated my Firefox Developer Edition to version 89.0b2 and now I just can not look at this browser anymore, "Inspired new tab design" is taking too much space and now became largest and at the same time least information-dense panel in my entire desktop! I searched around the web for a bit in hopes that I will find a theme or an add-on that will revert this particular change but no luck. I really want to revert to old UI look (at least tabs bar), there should be default theme or option to get back to old style. After some investigation I found userChrome.css but don't really want to install it (maybe this is actually the way of doing this kind of styling). Please help me revert UI design to old one.

Hi everyone!

When I browse the web with Firefox, it happens that the system becomes completely unresponsive. Some web pages seems to make Firefox using a lot of RAM and write a lot on the hard drive. I cannot actually say much more, because it not even possible to login in a console. The system is too slow and the console login times out... Firefox (or Web Content) writes wildly on the hard drive.

I used the Firefox provided by my Linux distribution (Linux Mint), but also the one downloaded from mozilla.org. The problem seems to be less frequent for the second, but it happend nevertheless.

The point is that this problem with Firefox happens sometimes, for example, when I forget the browser open on somehow demanding webpage (like in newspapers where there are a lot of media, graphics, and so on).

A point is also that I cannot replicate this "bug". If now I browsed the same pages that made the mess, nothing would probably happen.

I thought it had to do with the swap, but the system hanged both when the swap space was enabled and when it was disabled.

I saved a copy of the profile (and the cache) after the last crash, if they could be useful. The last time I had actually to force the shutdown of the computer, because there was no way to regain control over it.

Any ideas?

Thank you for your answers!

I have noticed that when I manually log in into accounts.google.com with no prior cookies in the browser and no association with a google account prior to that, it automatically logs me into sites like youtube.com, even with the strictest cookie policies (tried with Strict, custom+cross-site and custom+third-party). I do not particularly mind privacy wise since I'll log into them with the same account anyways, but as far as I understood, there should be absolutely no way this should happen. Cookies should be isolated by domain, I have uBlock Origin installed which prevents cookie sharing between domains by setting some CNAME records in subdomains (Uncloak canonical names), and afaik Firefox does not automatically read the google account cookies and share them around - if it did, that would be even more serious. So what is happening here and how can I change that? This seems to be a serious issue that I'm honestly not comfortable with out of principle since I chose the strictest settings.

Why can a stupid failing script on a web-page, or even intentionally so programmed script disable the copy (and sometimes paste) functionality?

How can this be disabled/fixed?

One highlights a text (any text) on some web sites, Edit menu allows Copy, context menu allows Copy, one hits Copy, nothing happens. It's not even a page where someone wanted to "copy protect" some information.

Copy and Paste should work just as advertised since those were invented, how hard can it be to get that right? Even stupid Notepad never fails at it. And no, I don't care what the idiot who programmed a page though would be/should be best for me, I want Copy to be copy, Paste to be paste. This used to work in "original" Firefoxes even when page developers wanted to make it not work.

And yes, while on a given page Copy fails miserably, at the same time in other pages it works.

I have updated the Two-Spep verification settings at my firefox account.

NOW, the mails I received have IP adresses with "Boardman, OR, United States", WRONG CONTINENT!

  • There is no other device linked.
  • The notifications mails with wrong location should be related to my setting update. There is no other mail that indicates my account changes.
  • My IP address is located to my country, I checked in firefox on a IP check website.

Looks like a problem from firefox!

Mails: 1. Account recovery key generated - correct, I did this in account settings

  • ... Germany - correct location and IP

2. Account recovery key removed - correct, I did this in account settings

  • Boardman, OR, United States (estimated)
  • IP address: 54.190.54.119"' 1:22:09 AM (PDT) Friday, Mar 19, 2021

3. Two-step verification enabled - correct, I did this in account settings

  • Boardman, OR, United States (estimated)
  • IP address: 34.214.206.92 3:12:14 AM (PDT) Friday, Mar 19, 2021

I activated recovery, deactivated recovery and activated Two-step instead.

The mails said: ".. your Firefox Account from the following device ...", my device is in germany, not "Boardman" US.

I am seriously worried!

The arrived Mail sequence is correct, I made these three changes. But what is happening with location and IP here?!

Firefox just updated today, and forced me to select a "theme". As near as I can tell, every theme makes all of my open tabs look like buttons--no outlines at all until I hover my mouse over them.

I'm sure some graphic artist decided that this was snazzy and minimalist and all that. But it really interfered with my workflow, to the point where I'm debating going to Chromium. I want *tabs*. I want a visual reminder that all of these things are open pages running in my background. Making them all look like buttons was ill-advised and (in my opinion) not smart at all. How do I get my tabs back?

It is bad enough that the upgrade was automatically loaded but on top of that, changing preferences including dumping my home page. Change privacy settings without asking ( to a lower level on top of that ).

Really POOR form.

Firefox 89 on my Raspberry Pi 4 is displaying what I'm guessing is a codec issue. Videos can be watched but the picture is corrupted by brightly coloured patches around areas of detail.

Prior to the version 89 upgrade, version 88 was working perfectly.

I have Firefox 89 on a Raspberry Pi and a PC. On the PC it still works perfectly, on the Pi video is displayed badly.

On the Pi Firefox 89 is running under Ubuntu 21.04. On the PC Firefox 89 is running under Ubuntu 18.04

Am I alone in this or have others seen the same issue ?

Assuming I am not alone, does anybody have any idea what has gone wrong ?

The Firefox account settings page displays a list of logged in devices at the very bottom of the page (connected services).

I have verified all logged in devices to be correct. However for one of the devices (my main computer browser), the location displayed is COMPLETELY off. I live in Norway, and it claims device location is somewhere in Oregon, United States. I do not use any VPN services and both my public IPv4 and IPv6 addresses are located in Norway, from which I connect with the device/browser in question (whatismyipaddress.com shows correct location for both of them). Also, activity timestamp is updated in accordance with my own activity from the client, but the location remains wrong. I also tried logging out the device, and logging back in, but this did not fix the location.

Obviously the location service used for the logged in device list is unreliable. I suggest that you please also show the latest IP address used by each device, so that more technically inclined users can verify correct addresses themselves, should the location be way off. It is unsettling to see strange locations (for known devices) on a page used to verify the security of my Firefox account. In this instance, there is no security breach, but it required me to spend much time investigating.

I do not know if it matters, but the device in question is a Linux desktop Firefox client.

as you can see in attached screenshot, there is a part of the interface ( toolbar ?? ) which is on the top of the viewing area , with possible possible overlay of some displayable elements ( as google ads on the right ).

disabling HW acceleration solved my problem, but is this can be fixed in a future update, I will be more than happy to enable it again.

After a crash, or even after shutting down the computer without closing all Firefox windows, Firefox will restore all the windows and tabs from the last session on restarting Firefox.

There can be many reasons why this may not be preferred behaviour for many users: Sometimes Firefox or the computer crashes because too many windows and tabs are open (and other applications running), killing Firefox may be a measure against malicious pages trying to hijack the browser, discarded pages after shutdown do not need to be restored, ...

So is there a way to make Firefox immediately ask whether to restore the session, like it already does after the second crash? This should actually be an option in the settings.

Firefox seems to have some threshold to leap to a larger font or a different font rendering scheme when adjusting the (Font) Scaling Factor in Ubuntu Tweaks. Nothing happens in Firefox windows until the Scaling Factor reaches 1.25 (125%) and then it jumps to render larger fonts everywhere. (next jump at 1.4) See the screenshots for the difference. What is this threshold? What is the actual parameter Firefox reacts to? Can I control it manually within Firefox?

This question has a rather convoluted background: I have replaced my 2560x1600 monitor with the 3840x1600 monitor and suddenly all Firefox windows render super ugly. It's not that they just look smaller due to to the smaller PPI but rather their font shape causes my eyes to tear. Previously the sensation was very soft. I do not know what that is but it seems it's not just the size. Could it be Firefox is using some information from the monitor that brings it to a sub-optimal font rendering/hinting/antialiasing behavior?

Increasing (Font) Scaling Factor to 1.25 via "Ubuntu (Gnome) Tweaks" app makes the fonts look acceptable again. Ubuntu Scaling Factor obviously also changes the size of other windows and their fonts. So I would rather keep the Scaling at 100% and just make sure the fonts are rendered in Firefox as before with the old monitor. I.e. I would like to remove this quality regression. The fonts can be controlled via Firefox properties but as expected this either increases all font sizes or doesn't work for proprietary fonts supplied by web pages (min font size). There should be a better solution than tweaking each font individually. The fact that the fonts are suddenly rendered acceptably again after the Scaling Factor reaches 1.25 makes me think that there may be some threshold in Firefox that makes it use different rendering scheme, mechanism or such. After 1.25 nothing happens until Scaling Factor reaches 1.4, then the font increases again. So can I just make Firefox render fonts as when scaling is at 1.25 but with the actual scaling factor at 1.0?

Apart from the overall size/resolution the monitors (old Samsung 305T vs. new Dell u3821dw) have different pixel pitch 0.2505 mm, PPI 101 (old) vs. 0.22908 and PPI 110,87 (new). Can this this be the root cause of the ugly fonts? So is there maybe a different parameter or setting to tell Firefox to render fonts regardless the higher PPI or lower pixel pitch?

I would expect everything to look just a bit smaller due to a smaller pixel pitch, but instead the fonts are rendered completely different and I can't find the setting that would fix that.

Just FYI I have been playing with these settings: Firefox: - Default Zoom 120% - Check Zoom Text Only - Minimal font size - layout.css.devPixelsPerPx 1 - gfx.font_rendering.cleartype_params.force_gdi_classic_max_size 100 Ubuntu: - Scaling Factor - System Fonts

I can't seem to install vsn 89. I have vsn 87.0 currently and Netflix won't run without an upgrade. Also, Amazon Prime requires Widevine, which requires a FF upgrade, so I need to upgrade. The best I have been able to do is download the tar file and run Extract on it. According to the file viewer, the latest version of FF is loaded, but when I run the program, it's still v. 87, not 89. The simplest method given is to open the 'About Mozilla Firefox' window and the downloader will run. But there is no downloader running when I do that. I would really appreciate it if someone would supply instructions that actually work.

BTW: I've looked for them, and I don't find the 'required' library items. But if these are truly required and I don't have them, how has FF been running at all these past months? I concluded that either they are installed but I couldn't find them, or they aren't really required at all. I've also tried Flatpack and it doesn't work either.

I am using Firefox on Linux (Ubuntu 20.10) to work from home over OpenVPN. Recently the VPN configuration was changed to use split tunneling to improve our internet connection. Since then I have had several DNS resolving issues in Firefox.

We use an on premise DNS server as an alternative to `localhost` domain names so we can access other developers' environments and so a few services can do the same. Our URL structure is like projectname.[optional personal identifier.]localhost.[type].nl. Without the [optional personal identifier], or when nothing is configured for it, the ip address is 127.0.0.1.

In Linux' OpenVPN configuration I have "Use this connection only for resource on its network" enabled for IPv4 and IPv6 is disabled (to benefit from split tunneling). With that enabled Firefox usually fails to resolve such development hostnames.

- As far as I know I do not have DoH enabled (and the about:networking log further down tells so too). - I do have `dnsmasq` enabled (with configuration for the above domain formats to route to 127.0.0.1 also) in an attempt to fix some issues before the split tunneling was configured correctly. And in an attempt to try and get Firefox to handle these DNS resolving issues. - `dig` on the command line for the same domain works just fine. - Adding hostnames to /etc/hosts works. But that's becoming a chore, working on dozens of projects over months.

Why is Firefox failing to resolve such domain names? Should I just create a Bugzilla issue?

I created a log with about:networking set to `timestamp,nsHostResolver:5`:
