Firefox supportforum

I got a second hand HP Spectre x360 (2015) today which came with Ubuntu 20.04 preinstalled and it seemed fine at first but when I connected to the internet I found Firefox to be incredibly slow to load any site I tried to access. Trying to watch a video on youtube took about two minutes to load. Facebook and Gmail both refuse to load properly at all. No matter what site I try, it seems to take at least 30 seconds to load, if it loads at all. This might be the slowest computer I've ever used, and I remember the 90s! I know the internet connection isn't the problem since my other devices work perfectly. I tried to download some other browsers (Chrome, Opera, Vivaldi) to see if Firefox was causing the issue but they all failed to download properly (error message "failed to install file: not supported").

I'm at a loss. I've tried searching for answers online which suggested fiddling with the proxy settings and going to about:config to toggle the "network.dns.disableIPv6" from "false" to "true". and nothing seems to have helped so far. Any ideas please? I like the computer but it's totally unusable for me at this point.

I installed Linux version Firefox on Chromebook relying on this instruction: https://support.mozilla.org/en-US/kb/run-firefox-chromeos?utm_source=www.mozilla.org-firefox-browsers-chromebook&utm_medium=referral&utm_campaign=seo

and I cannot type any letters other than English alphabet, even though I've set OS and input language to Korean. Problem is consistent to other typing language, except some languages that seems to have letters from alphabet combination.

While it seems that it's normal that some Chrome OS keyboard shortcuts are not compatible on Linux application, I'm not only unable to switch input language on Firefox but also not able to type any Korean letters after switching the input language outside Firefox.

Firefox Nightly cannot be found in the 'Software' store, so probably the only way to download it is by going to the website and getting a tar.bz2 file. I got that, extrated it and placed it in the/opt folder, made an application shortcut, added an icon, and now it's working like a normal app. The problem arises when it tries to auto-update. Firefox Nightly updates very frequently, sometimes more than once per day, and on windows, I used to get a notification saying that a new update is released, and if i wanted to install it. Clicking yes, Firefox would update and restart within moments, and restore all my tabs and windows seamlessly. Here on Linux, I have to manually download the new tar.bz2 file, extract it, replace it in the specified folder, and launch Firefox Nightly again, and again and again usually once per every alternate day, whenever the new update comes. Is there a solution for this? Will Firefox someday release a .deb file for easy installation and updates? My PC : Dell Optiplex 3070 OS : Zorin OS 16 Core (based on Ubuntu 20.04 LTS)

My bookmark creation is broken. I'm using Ubuntu, also cleared the cache, uninstalled/reinstalled. My existing bookmarks are still there. "Bookmark This Page" in the search bar does not work. Troubleshoot had the same broken bookmark prob.

The Home page row of shortcuts are all blank.

Another weird thing is FF doesn't show up in my apps. I just added another FF, which had the same problem and deleted it.

Manage Exceptions button for cookies is not working for me since FF88 or 89, don’t remember which version precisely. I click on the button and the dialogue box that would normally appear to set exceptions does not pop up. Moreover it looks like when I click on the button the user interface on that tab freezes for a period. My FF profile is customised. I know if I start with a blank profile the issue goes away. I have another that works fine. However I would rather try to fix this issue in my current profile. I poked around in about:config but so far have had no success.

Any ideas? I searched google but could not find anything. Also checked mozilla bugzilla a while back without success. I am using FF 92 on Arch Linux.

Hello there,

I have been having a problem with my Firefox installed on Ubuntu, I have attached a screen shot to save the time of explaining what is happening, because I'm honestly not sure. Seems that some website have some problems being rendered.

Versions:

Firefox: v 92.0 (64-bit) Ubuntu : Ubuntu 20.04.3 LTS

Appreciate all the support.

When i click on the lock icon in the address bar, nothing happens (I would expect to see the encryption and certificate, but no widget opens). When I right-click into the page and select "View Page Info", "Security", "View Certificate", no certificate exists. Only generic info is shown (Servers+Authorities). Also an error is reported in the system log, confirming that no certificate exists: JavaScript error: chrome://browser/content/browser-siteIdentity.js, line 642: TypeError: issuerCert is undefined

Questions:

• Why does Firefox show the lock icon while no certificate exists?

• How does Firefox establish a secure connection without having a certificate? (From my understanding a certificate is needed for TLS to work.)

Version used: Firefox 78.12.0esr ('Mozilla/5.0 (X11; FreeBSD amd64; rv:78.0) Gecko/20100101 Firefox/78.0'), no add-ons or plugins.

I use an online mail account. Recently when I write an email Firefox flags every word as misspelled. Firefox seems to be using a French dictionary thought I set English and Japanese as languages for Firefox to use. How can I correct this?

Hi there, I have a laptop with a fresh Debian install which includes Firefox ESR but I have encountered a bug that I cannot get past.

I guess to put it simply - I cannot browse to necessary areas of an extension that have a menu larger than my where my screen cuts off.. Please see this picture I have attached: https://imgur.com/OzMhWue

In this picture, there is options and buttons I need to select to proceed that are below where the screen cuts off. I have not found any way to shrink this, nor navigate to the missing area. Clicking the scroll icon only scrolls the background website but NOT the menus itself. I am encountering the problem with all major extensions including Lastpass and Metamask - so I assume this hopefully has a solution!

Hi, I've been having issues with Firefox for some time now. Every page I got to throws a NS_ERROR_NET_INADEQUATE_SECURITY error. I cannot fix it by setting network.http.spdy.enabled.http2 to false is because Firefox then starts crashing. In the past I've gone around the error by turning http2 off, but recently, first the developer edition, then after today's update to 91.0-0.1 of stable version Firefox crashes if I turn the feature off.

The developer Edition started throwing NS_ERROR_NET_INADEQUATE_SECURITY sometime in spring, then started crashing in June I think. The stable version followed soon as described above.

I am submitting this ticket from a beta version, which for some reason does not have this issue.

I thought it may be the Linux version of Eset, but removing it did not help. I cannot think of any other reason why am I getting those errors, but it seems I am alone because my colleagues don't seem to have this issue neither on macOS, nor Windows.

Hello, I'm using FF 68.12.00 ESR (Linux x64). Any page at addons.mozilla.org looks like the attached image. No visible text. Other pages look ok.

Version 92.0 (64 bit) Ubuntu: 18.04, 20.04

For a couple of months, I have not been able to resize the FF window. Consequently, I abandoned FF for Chrome. I've just upgraded my os to Ubuntu 20.04 (from 18.04) so I thought I'd try FF again. The problem persists.

Minimize/Maximize work fine, but when non-maximized, the resize "handles" don't show up (see attached image). I've tried safe-mode, as suggested by some previous post, but it hasn't helped.

Hello, Since yesterday (Sept, 28th 2021), I have the following message when trying to preview an attached document (PDF, in this case), accessing Hotmail using Firefox 92.0 (64-bit) in UBUNTU Linux:

"Something went wrong while the document preview was being created. Please try again later"

The same error also occurs using Firefox 92.0 (64 bit) in Windows 10, but does not occur using Chrome in UBUNTU and Chrome in Windows, as well as using Microsoft Edge. Can you help me please?

Thanks in advance. Manoel.

Hello,

I updated firefox and it's now hard to tell when one tab ends and another begins when you have multiple inactive tabs next to each other, which is a major annoyance.

The way to solve this would be to have the inactive tabs have a border around them like the active tab, have them have a different background color from the toolbar, or otherwise have some kind of separator between them. I saw another answer that gave a temporary solution, but the same answer said the solution was going to stop working in a future update. Is there a permanent solution?

Hey there,

for a while now we have problems loading our page https://risofort.press/ in firefox: the header will always load, the body of the main page and sub pages will infrequently load, and after having loaded once it will not reload for a long time (like, weeks). all of this works in other browsers. After contacting our host and trying some stuff like deactivating plugins to see if one them is causing it, I am realizing that perhaps it is the way our theme is loaded by firefox - a similiar issue was resolved here: https://support.mozilla.org/de/questions/1320526#answer-1381654

However I can't figure out what part of our website is the one that is keeping the main area to be loaded, or become visible, rather.

Any thoughts on this very welcome, thank you! Will also pass this question on to the theme authors.

Thanks in advance, L.

Okay, PopOS 21.04, Firefox 92.0 x64, my packages are up to date, my graphics card (Nvidia 1080) drivers are up to date (nvidia-driver-470 (proprietary)), kernal 5.13.0-7614-generic.

I run a variety of addons, but the only ones that should even be touching YouTube in any way would be Noscript, Ublock Origin, YouTube HD, HTTPS Everywhere. In the past with my current configuration none of these have given me any issues with playback.

I don't have any idea why, this is a problem I experienced a long time ago and now newly the other day for seemingly no good reason, videos on YouTube but also the web in general will not play until I open Firefox, close the browser, open it again, and then try and do whatever it was I'm trying to do. While not a fatal issue, this is one that is extremely annoying and I really don't feel like putting up with it.

Anyone have any advice or information?

Firefox leaves full-screen mode when window manager remaps window to be in a frame and re-sizable.

In the window-manager that I use (KDE plasma), I can ask the window-manager to exit full-screen mode, without telling the window. This allows me to tell a window to be in full-screen mode, while in a framed window. I have attached a screen-shot of chrome showing a youtube video. Both youtube and the chrome are in full screen mode, however the window manager has re-sized it and added decorations (title-bar&frame), and is allowing me to resize, move, minimize, maximize, etc.

This works for every program that I have used (that has a full-screen mode). However it is not working for Firefox. It seems that Firefox is triggering off of the wrong event.

My guess: the window-manager sets NET_WM_STATE_FULLSCREEN to enter full-screen, and would normally clear this attribute to exit full screen. When we exit full-screen, but stay in full-screen mode, the attribute is not cleared. However Firefox is triggering off of something else such as a re-size event.

Use-case: What I am trying to do

1. Enter full screen mode: browser hiders tab-bar, and address bar, maybe web-page changes layout (e.g. you-tube resizes video player to fill window)
2. Tell Window-manager to leave full-screen-mode, but not inform browser (or other app). Browser is now still hiding tab-bar, address-bar, site is till showing video in whole-window, but window can be moved and re-sized.

This works for every other app that I have user. (Some apps don't have full-screen-mode, so this does not apply to them. But it works for all that do have it.)

Firefox displays the ebay.co.uk website in some sort of text-only mode. It's unusable.

I've fixed this problem in the past by turning off the Enhanced Tracking Protection. It was ok for a while, but today it's broken again.

And ETP is off, but the site still doesn't work.

whenever i log into a official site such as Georgia DOT or Dish Network as i did recently, it is telling me that the Google (that is used as a search engine) is out of date and must be updated. as well, if i try to go to Netflix it tells me the DMR is out of date. computer set for auto update so i don't understand why. please help.. thank you.
