I'm on Linux.

I've been using this method to setup a custom new tab page for Firefox for almost 4 years, and it has worked great: https://jamesnorth.net/knowledge-base/article/firefox-new-tab-page

---

Navigate to /usr/lib/firefox.

Create autoconfig.cfg:

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

/* set new tab page */ try {

 Cu.import("resource:///modules/AboutNewTab.jsm");  
 var newTabURL = "file:///home/james/ff/index.html";  
 AboutNewTab.newTabURL = newTabURL;  

} catch(e){Cu.reportError(e);} // report errors in the Browser Console

Create defaults/pref/autoconfig.js:

// pref("general.config.filename", "autoconfig.cfg"); pref("general.config.obscure_value", 0); pref("general.config.sandbox_enabled", false);

---

However, upon updating to Firefox 136, I only get a blank page. All of my autoconfig files still exist in /usr/lib/firefox.

When I create a new tab with Ctrl+T, it's a blank page. When I create a new window, it loads the local page I want it to load with the file path in the URL (which it never had before; the URL bar was blank in Firefox 135). So it seems to be partially working.

Any tips?

Solved: Issue appears to be resolved since update 136.

The appearance of search suggestions changes to a bloated and verbose style whenever the window is not maximized (and it's width is less than twice of the longest first part followed by a dash of the quicksuggestions - in white font in the screenshots).

Observed since update 135 (from 134). Also no custom userChrome.css file is used.

How to keep appreance consistent / compact / normal (in all window-sizes)?

Preferably without a custom userCrhome.css file. I looked through all results on urlbar.quicksuggest in about:config but couldn't figure out any helpful setting.

Related threads/questions/keywords: search, urlbar, suggestion, quicksuggest, bloated, style

If I turn on the HEVC transcoding option on in the Plex settings, and watch a video that uses the Transcoding, Firefox will have a very small black bar at the bottom (might have also impossible to see black bar on the right to keep the aspect ratio). No issues when using x264.

I don't know if this is a Plex or Firefox issue, but it doesn't show up with other players/browsers that I've tried.

The attached screenshot is taken from the bottom of the video by using PiP against white blackground.

Websites keep telling me I have an ad blocker on. I do not have an ad blocker, and even when I disable all extensions, I still get the messages that I have an ad blocker. YouTube no longer works on Firefox, which I suspect is for the same reason.

When I restart the system after a refresh or after shutting down, Mozilla takes FOREVER to connect/load webpages. (I can get on-line immediately after a reboot using Chrome, however). It is extremely frustrating as I have to leave the system on a webpage all day long and over-night so as not to have to go through the hassle of trying to get it to connect after an absence. Even when Mozilla requests I re-start for an update, it still takes forever. what is causing this and how can I fix it? Be advised, I'm not a computer whizz so please explain in non-tech talk. Thank you, Joe

I've been using the firefox pdf viewer for quite some time and it's worked quite well. Within the last few days though I've developed an issue.

When I open a pdf it opens correctly for just a brief second (standard text, white background, nothing unusual) and then switches to something like the attached image (black background/ text and such). I have not changed anything that I'm aware of, though I did just recently install a new firefox update (136.0 64-bit windows 11). I didn't notice any articles or comments about this particular issue here yet, so figured I'd ask for some help.

Anyone know how to resolve this? Or other things I should look into?

Thanks for your time, Derek

I'm used to manually update firefox browser on my windows 10 pc, everything was fine before, but I found a strange situation about two weeks ago, the situation has occurred twice so far --

For the previous version, I manually download update in settings, firefox browser can be restarted but not updated after clicking restart firefox button, and an error notificaion firefox being updated by another instance appeared instead of 'check for updates button, then the update process started when I exit firefox browser and reopened it.

For the latest version, the strange situation occurred again when I tried to manually update firefox browser, the only difference is that I don't see the error notification from last time.

Why does the situation happen? Do it cause any risk? How can I fix it?

Firefox continuously hangs and locks up. It has 15 or 20 processes running and then stops responding when I click on a link. I shut down Firefox and restart and it runs fine. I restarted this session 10 minutes ago and searched for "Limit Firefox sessions" and it already has 14 processes running.

Something is wrong with that.

In "Performance", I Unchecked "Use recommended performance settings" and checked " Use hardware ..."
