I'm on 76.0.1 and Firefox for some reason stopped showing youtube thumbnails. Other browsers show them perfectly fine but since Firefox is my main browser I would appreciate some help with this problem. Exactly this issue: https://support.mozilla.org/en-US/questions/1271112 As soon as I delete the site-specific configuration data, from the History option on bar menu, the thumbnails come back inmediately, no reload needed. But when reload the tab, or open a new one, the thumbnails dissapear again. Thanks in advance for the help.

New Tabs and even sometimes first tab do not load any page and become just "dead"

Open in New Tab and Ctr T is like a roll of dice now, the same page sometimes loads sometimes doesn't, usually closing FF and re-opening solves it.

This has been happening quite frequently so I tried several builds and solutions, uninstalled and reinstalled with new profile, safe mode, no add-ons or themes, both 32 and 64 bit, ESR, etc.. (I'm on Win10 64 bit)

If anyone is experiencing something similar or have an idea let me know please I've been using Firefox for longer than I remember and I would hate to switch now

FF didn't used to be so slow. It now get really slow and uses a lot of RAM to the extend that my disk is full and I have to shutdown FF.

I do have like 30 tabs open, with one or two Slack-like web apps. However, I'm not using them all at the same time. In the first couple of quantum releases it didn't used to be this slow, never mind pre-quantum performance. Oh and I'm not gonna compare to Chrome or Chromium.

Any help with this? Is it the extensions causing it?

  • Also I never found a proper replacement to legacy Tab Session Manager (the quantum one is no where near as good).

Hey there,

i recently upgraded from a mid-2010 macbook pro to a mid-2017 one, migrating all my data from a time machine backup. everything seemed to work seamlessly, but then i figured out that firefox doesn't show some pages, for example the video-streaming platform "chili", instead only blank pages show up. i already tried safe, which doesn't help. when i try to delete all my history and empty the cashe etc. firefox crashes continuously.

i figured out two things so far: first i changed my macbook user account and tried the same website in firefox on my guest account. here it worked. then i went back to my normal admin account, i deleted my firefox profiles folder and reinstalled firefox. now it also worked here. unfortunately this would make me lose all my settings and data, which i don't want, so i put a backup of my old profiles folder back in place to keep all my stuff, but the blank pages error remains.

if anyone could help me, i'd be super grateful!

thanks so much :) Miro

Hello,

It's been a while since the release date of chromecast on browsers.. Today, year 2020, all the chromium based browsers add chromecast (Edge, brave, chrome, etc..). My favorite browser is firefox, and i am forced to use a chromium based browser to cast to my androidTV's. Sometimes i think to leave this browser and use a chromium based all the time.

I searched and installed chromecast extension to firefox and nothing works to me, and they are not user frindly as chromecast extension on chrome.

Can you tell me if you even think in add a chromecast extension in firefox by default?

Thanks,

Hello,

Sometimes Firefox is having a wrong IPv6 in cache. Using the extension SixOrNot, I can see for rss.forumanalogue.fr the following IPv6 2001:41d0:fecf:8900:216:3eff:fe65:97bc, with the note "Cache". However, this IP corresponds to toot.forumanalogue.fr and the actual IPv6 for rss.forumanalogue.fr is 2001:41d0:fecf:8900:216:3eff:fef1:20a2. In order to temporary fix the issue, I perform a dig and it solves the issue for a while.

It is a rather new issue (few weeks).

What is going on?

Since reinstalling Windows, I can no longer change my bookmarks in the order I want. Every time I try to put the bookmarks in order, the links jump back to a different position. However, not in an alphabetical order, but according to my own rules, completely confused. So I have to look for everything now. What can trigger something like that?

Hi,

I'm trying to change the theme (only using standard dark and light themes) from a linux terminal. My attempted routes include changing a user.js file (the rest of the file works), in particular setting extensions.activeThemeID (I've also attempted doing this in about:config, as well as editing the extensions.json file).

I can change the theme by going to add-ons in a browser. This works fine. I was hoping to automate it (it's not the 1980's - clicking three times to change to a default theme seems unnecessary).

Am I missing something that must be changed in about:config or any other file to change the theme? The extensions.activeThemeID changes when changing the theme in add-ons and seems the likely option but does nothing if I change this value myself.

Hello.

I use 76.0.1 (64-bit) on Xubuntu 20.04 and same thing happens on every computer. After clean system shutdown or restart, Firefox keeps restoring tabs I used. This never happens if I close Firefox first. Also this never happens when I close and reopen firefox in the same session. I tried everything: - obvious "Restore previous session" restore in options - about:config turning various options: browser.sessionstore.resume_from_crash browser.sessionstore.restore_tabs_lazily browser.sessionstore.resuming_after_os_restart browser.sessionstore.max_tabs_undo browser.sessionstore.restore_on_demand privacy.clearOnShutdown.sessions - i even created "user.json" with restore line as someone suggested None of these measures helped. I thought that It may be connected to XFCE session store somehow, so I went through disabling that too - no change. No other program happens to do the same. After reboot, when someone starts Firefox, all my tabs from previous session are reopened instantly. This happens on my both Xubuntu workstations, but never happens on my Windows computers. Please help.

hi guys and girls of mozilla,

ive a little issue with a custom homepage i made which i want to use as my new tab page. im on linux and use firefox 76.0.1 (64bit).

i set up a autoconfig.cfg file with this code:

// var {classes:Cc,interfaces:Ci,utils:Cu} = Components;

  • set new tab page */

try { Cu.import("resource:///modules/AboutNewTab.jsm"); var newTabURL = "/home/joe/.mozilla/firefox/h75u1z1z.default/startpage/index.html"; AboutNewTab.newTabURL = newTabURL; } catch(e){Cu.reportError(e);} // report errors in the Browser Console

i also set up a autoconfig.js file with this code:

// First line should be a comment pref("general.config.filename", "autoconfig.cfg"); pref("general.config.obscure_value", 0); pref("general.config.sandbox_enabled", false);

theyre saved in lib/firefox and lib/firefox/defaults/prefs

i then put firefox to open new tabs with a blank page. now it works like this. when i click open a new tab i get a blank page. but in the urlbar is the file selected. now i only need to press enter and i have my new tab page.

the question now is- how can i force firefox to press enter for me. that it opens the file directly and doesnt need me to press enter.

can u spot any errors in the code i copied from a thread in reddits/r/firefox CSS forum?

or is there a setting i can change which makes it the page opens by itself?

ill add two pics- one when i just opend the new tab and one after i clicked enter
