How to find out which Firefox extension caused page issues, like errors, e.g. CSP - Content-Security-Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). ?

SHORT STORY:

I have been able to find extension behind errors shown in dev. console (F12 key) like CSP ones (mouse hover over the link near the error on dev. console (F12 key), Console tab, to see moz-extension://somestring and find first characters of the string at page about:debugging#/runtime/this-firefox) But is there any better/easier way to find out web page issue causing extension?

LONG STORY:

Website fails to load (but in a Private window loads OK). F12 key in normal window, Console tab, shows:

SyntaxError: redeclaration of let settings

clicking it, it further show:

abc123-def456-...-...-....:1:1

   <anonymous> blob:moz-extension://8834...

inject resource://gre/modules/ExtensionContent.sys.mjs:581

   AsyncFunctionNext self-hosted:852


when i search for mentioned 8834 (first letters of a long string) at about:debugging#/runtime/this-firefox (i get there clicking settings wheel at about:addons and "Debug addons".) then i find Chameleon extension.

So I try to pause extension in its menu, that not helped, but disabling whole extension in about:addons removed errors, yet page still does not load. 4 remaining CSP errors like:

Content-Security-Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). contentScript.js:160:48951 ...

when I mouse hover over the hyperlink "contentScript.js:160:48951" the browser status bar shows extension address and when i memorize first letters of the address and search it at mentioned about:debugging#/runtime/this-firefox tab, i find: Phantom (cryptocurrency wallet) Metamask (cryptocurrency wallet) Phantom (cryptocurrency wallet) Violentmonkey (provides userscripts support for browsers - I am using it only for https://github.com/Owyn/HandyImage which is disabled currently)

I have tried to didable all these extensions causing removal of a CSP errors, yet page still does not load in normal browsing window (in private does). Normal browsing window shows only one warning/error:

Source map error: Error: NetworkError when attempting to fetch resource. https://firefox-source-docs.mozilla.org/devtools-user/debugger/source_map_errors/ Resource URL: moz-extension://extension address here/browser-polyfill.min.js Source Map URL: browser-polyfill.min.js.map

when i search for the extension address first letters at mentioned page about:debugging#/runtime/this-firefox i find "Textarea Cache", disabling it does not make page load.

After re-enabling disabled extensions and restarting Firefox, page started loading. I suspect (likely wrong) that the python application which is serving local web page in question had exhausted connection limit for the normal browser window/process, but the private browser window process was OK.

What i can do better to discover the causing extension or other cause of failed loading page?

Hey,

I'm looking for a shortcut/hotkey to focus the page.

The best I found is "Move to Next Frame", which is F6. When having the URL bar as focus, and no bookmark bar open, this will focus the page.

I have two questions here: - Is there a better way to focus the page? - If not, how can I remap F6 to a more usable hotkey?

I have found some threads with workaround like tabbing 2-3 times until the page is in focus. I'm looking for a single shortcut, having to press a key multiple times kinda defeats the purpose of a shortcut.

I have found information on how to remap hotkeys with either extensions or autoconfig, but I can't find which key I have to change. Extensions don't seem to include this key.

For autoconfig, I looked through view-source:chrome://browser/content/browser.xhtml and the Browser Toolbox to find this shortcut, but with no success. Maybe I looked at the wrong spot, maybe not all shortcuts are listed there?

Any help is greatly appreciated.

Hi,

I was working on my work on a Google Doc, and when I tried changing the font, Firefox immediately crashed after clicking the font box. When I restarted, Japanese characters turned into boxes with codes in it. I have the Japanese language installed on my system and it works fine on my system. I also have the Japanese language installed on my browser. Other characters appear as the same thing, but I don't know for sure what they are other than Chinese and Korean. My cursor also changed to what looks like a hand pointing at something whenever I hover over something, however I am unable to provide a clear screenshot of that so I can only provide pictures of the messed up Japanese characters.

How would I fix this?

Firefox 100.0 Ubuntu 22.04 Mozilla VPN 2.8.0

As the title says, Multi-Account containers doesn't detect the VPN, which means that it's not setting the VPN for specific containers.

I suspect this is actually a problem with the "Allow extension to exchange messages with programs other than Firefox" permission. Could be a VPN issue, but gut feeling that it's a Firefox issue, TBH

Anyone else seeing this?

Linux distro manjaro, in its gnome edition, ships firefox along with a separate package called firefox-gnome-theme-maia which alters userChrome.css, userContent.css and some about:config entries to entirely change the appearance of the browser. This package is preinstalled in the gnome edition of manjaro, along with firefox browser (screenshot ). They claim that it does not infringe upon mozilla's trademark guidelines as it is a separate package and can be removed by the user, though it is not mentioned in instructions. However it significantly alters UI and UX, while still using Firefox branding and logo.

I got help with this from your group some weeks ago, but I had to reinstall my Ubuntu OS (linux v.20.04.4 -- using firefox) recently and can't recall the answer.

When I view a WikiSpecies list of file names (e. g., see https://species.wikimedia.org/wiki/Pentatominae), the instances which have been installed but never used should be in a different (reddish) color. I am attaching an image of a page containing a file named "Abadia" (first one on the left, just under "A") which is unused. I also am attaching an empty "Creating Abadia" which is the result of clicking on "Abadia".

Please tell me how to change the image of an unused, empty file. I recall that there were two different choices SOMEWHERE in the system, "Always" and "Never" I think: One of them forces a system-level color pattern which includes reddish unused items; the other allows the used to program arbitrary displays such as the above (typical example from the dconf editor is 'bg_color: #f0f1f2; selected_bg_color: #023C88', but this editor does not change the appearance of a file instance.

Monospace font not being chosen correctly when font-family starts with missing fonts

I've just started noticing in Firefox 99 on Arch Linux that Firefox is using the wrong font when the font-family is given as "ui-monospace/other fonts..., monospace". This looks similar to the issue mentioned here: https://support.mozilla.org/en-US/questions/1351497

The inspector for these websites underlines "monospace" as the active font, but then uses a non-monospace font (in my case, Bitstream Vera Sans) to display the content. This does not happen when the font-family is "monospace,monospace" or "monospace". I can't quite figure out exactly what causes the font to be chosen incorrectly: sometimes it does show up if I have the preceding fonts installed, e.g. Consolas or Liberation Mono, but other instances do not look as intended.

Currently, I have fontconfig set up such that: $ fc-match :family=ui-monospace VeraMono.ttf: "Bitstream Vera Sans Mono" "Roman" $ fc-match :family=monospace VeraMono.ttf: "Bitstream Vera Sans Mono" "Roman"

Firefox's fonts in about:preferences are configured as all defaults: Serif: Bitstream Vera Serif Sans: Bitstream Vera Sans Monospace: Bitstream Vera Sans Mono

I'm stuck at ver 88. Starting with 89 I seem to be limited to around 150 total tabs across all open windows (even if only one is open). Total lockup of the desktop (KDE in linux) It hadn't been a problem, I just shut off auto update.

Now websites are whining about me running an older browser and some are even refusing to let me in. So I thought ok, I'll run multiple instances and keep the total number of tabs low. 5 instances work fine, the 6th starts to act a bit flaky, 7+ is a total lockup of the desktop (KDE in linux).

Even if I can manage to kill the last instance, its corpse remains on screen.

So I'm back to ver 88 with no solution. Is there a way around these limits? When I'm doing development I often have more than 600 tabs open. Eventually some will get closed, but I can't very well get much done if the browser is just going to lock everything up.

I'm running the latest version of Firefox on Xubuntu 20.04.

Thanks to some help from others long ago, I've been assigning custom icons to my toolbar bookmarks for quite some time. This is done in the appropriate profile directory (~/.mozilla/firefox/<profile>/chrome) by placing a 16x16 pixel PNG icon in an icons sub-directory, and then creating entries in the userChrome.css file. Here is an example:

.bookmark-item[label="Google"] image {

   margin: 0px !important;
   padding: 0 0 16px 16px !important;
   background:url("icons/google_01.png") !important;

}

.bookmark-item > .toolbarbutton-text { display: none !important; }

The first entry assigns my custom icon "google_01.png" to a bookmark with the text label "Google". The second entry makes sure that the text labels are not displayed on the toolbar.

This works great for bookmarks on the toolbar. I decided to create various folders and consolidate groups of bookmarks. I created a google folder with the label "Google" and it gets the custom icon I have assigned. However, the various bookmarks placed within the folder (Maps, Gmail, Calendar, Contacts, Drive, Groups, Search), each with unique userChrome.css entries of their own, and which displayed as desired when on the toolbar, often lose their custom icon when placed in the folder, getting the icon assigned to the folder itself repeated for these entries -- but not always! For example, given:

.bookmark-item[label="Maps"] image {

   margin: 0px !important;
   padding: 0 0 16px 16px !important;
   background:url("icons/maps_01.png") !important;

}

.bookmark-item[label="Gmail"] image {

   margin: 0px !important;
   padding: 0 0 16px 16px !important;
   background:url("icons/gmail_01.png") !important;

}

.bookmark-item[label="Contacts"] image {

   margin: 0px !important;
   padding: 0 0 16px 16px !important;
   background:url("icons/contacts_01.png") !important;

}

.bookmark-item[label="Drive"] image {

   margin: 0px !important;
   padding: 0 0 16px 16px !important;
   background:url("icons/drive_01.png") !important;

}

.bookmark-item[label="Groups"] image {

   margin: 0px !important;
   padding: 0 0 16px 16px !important;
   background:url("icons/groups_01.png") !important;

}

The Maps and Groups bookmarks get the desired icon displayed, but the remainder just get the google_01.png icon assigned to the folder. This kind of random working/not working repeats for every other folder I create.

So I'm wondering if anyone has a clue as to what's going on and how I might better rewrite the bookmark-item entries to get the icons to reliable display when located in toolbar folders.

Thanks.
