Hello everyone,

Why some Wikipedia pages cannot activate reading mode under Debian 12 and Firefox ESR 115.9.1, for example this English Wikipedia page on Emmabuntüs does not allow reading mode to be activated while French, Spanish and German pages can ?

See our test video on this subject: http://share.emmabuntus.org/Accessibility/Firefox_mode_lecture_non_disponible_emmabuntus_en.mp4

Is there a utility to test pages compatible with reading mode?

Or otherwise in which Firefox log file to see if a page is compatible or not?

Thanks in advance for your help.

I tried redownloading Firefox after I saw that i was unable to download any extenstions/add-ons. Anytime i try to download something from the firefox browser, the download fails or gets cancelled. I never changed any settings, how can i fix this?

My default search engine is Duck Duck Go. I frequently use a VPN.

I am usually in North America and want to search sites in North America. When I run a search by typing a search term in Firefox, I get results beginning in UK, and I see that a blue toggle switch has been set to UK. (See image.)

This started 2-3 weeks ago.

How do I set things so that my searches begin in North America?

I have checked "about:config" preferences and do not see anywhere that UK is specified. I don't see a region preference setting, either.

Thank you.

I installed one of the ad blockers, I can't remember which one. It's given me so much trouble that I thought to disable or delete it. I deleted the little icon ( a stop sign) that shows up on the far right of one of the menu bars (don't know the name of that bar but here it's the second one down). But websites still complain that I have an ad blocker. I've gone to 'add-ons and themes' but I can't find it. BTW, what's the difference between an add-on, a plug-in and an extension? Which one of those are ad blockers? How can I see and then delete whichever blocker I still have? Without the icon I can't even disable it for individual sites.

Hello dear community,

I have a program that continuously monitors the download folder under Windows 11 for a specific file and retrieves it. I download this file in Firefox, but the said program gives an error.

I have noticed that when files are downloaded in FireFox, they already appear in the Downloads folder with the corresponding file extension with 0 bytes and these are then apparently swapped or merged with the .parts file.

The problem is that the mentioned program now tries to retrieve the unfinished file, which then leads to an error.

Does anyone know if it is possible to customize Firefox so that the file only appears in the download folder when the download is fully complete?

Many thanks for your help :D

Firefox browser, v123.0.1, 64-bit. windows 10 Pro, 22H2.

Hello, this may not be a problem with Firefox itself at all, but I'd like to try to understand what the cause of the problem I and others are having.

I have Norton 360 installed, in this Windows 10 computer and like to use Firefox for internet browsing, it has always served me well.

I also have Norton Safe Search integrated/add-on to Firefox. This puts a red, green, or gray check mark at the end of each link that comes up during a search and has always worked before.

Recently, I've noticed that such check marks do not appear at all when doing a search with Firefox, but they are present when I do searches with MS Edge.

I am searching for a solution here, and also in the Norton Community. There are others there who have stated they are having the same problem.

Has anyone here heard of this before, would you have any suggestion as to what may be causing the lack of the Norton Safe Search check marks in Firefox searches?

Any input/suggestions would be welcome.

I am using Firefox 123.0.0 (rel. 20-Feb-2023) on a Win 10 Pro v22H2 computer.

I understand that FF123.0.0 is supposed to include a new option to "Report Broken Site" on the menu (hamburger icon) that is described in the support article How do I report a broken site in Firefox desktop? but I can't see this new option. I also checked the menu options under More Tools and Help but can't find it.

Exiting and re-opening Firefox didn't solve the problem.

Hi All,

For some reason my tab icons look a little low, and I would like them more vertically centered.

I've been trying to move these icons around using some older code that doesn't seem to work anymore.

The code below no longer has any effect.

Does anyone know how to move the tab icons up 1 pixel?

Thanks!

/* padding doesn't move them */
.tab-throbber, .tab-icon-image { padding-bottom: 4px !important; }

/* margin doesn't move them */
.tab-throbber, .tab-icon-image { margin-bottom: -2px !important; }

/* can't even turn the icons off LOL */
.tab-icon-image { display:none !important; }

Hail all:

OS: W11Ent_x64 V: 22h2 (b: 22621.3447) FF: 124.0.2 x_64 I tried several "Group Tabs" add-ons, like: Simple Tab Groups. Tab Group. And I few I can't even recall the name from. Yet, none works. Not ONE.

Now, I use Edge as well, on my corporate system that I got from work. Personal PC I use FF on.

But, the Edge Tab Grouping, which allows tabs to be "put to Eco-Sleep", while hidden the open tabs by clicking the Group-Tab Icon, is a feature I sorely miss in Firefox.

Odd, as, so many requested this feature, how come it has not been implemented over the many years of people asking?

Either way: Does anyone know a good, WORKING add-on that does the "Edge Thing" with FF tabs, please? Since, I often got like 200 tabs open, which is a real misery without Tab Grouping and "Hiding".

Thank you aforehand: Ke'Ylan.

The Amazon.co.uk search plugin was working but now its not and when i try to click "add search engine" a box pops up with

Firefox could not download the search plugin from: https://d2lo25i6d3q8zm.cloudfront.net/browser-plugins/AmazonSearchSuggestionsOSD.Firefox.xml

another post suggested checking the about:config browser.search.region mine says "GB" which would be correct for .co.uk

All other search plugins work fine. Any suggestions?

I view a lot of pdf documents via firefox, the light gray background makes my eyes and head hurt after prolonged usage. In the past I found a solution on this forum that advised to set pdfjs.viewerCssTheme to "2" in about:config. This set the background of pdf viewer to black/dark gray. This has worked for years until recently when the pdf viewer switched to light mode again (pic 1). I checked the about:config settings for pdfjs.viewerCssTheme but there appears to be no change. I tried restarting the browser, setting the theme to 0 and to 2 again, updating browser. Sadly the theme is still light gray. Is there a way to change it again? The desired outcome is in pic 2. I do NOT want to change the color of the pdf pages themselves.

I added my own shortcuts and deleted all the preset ones (Wikipedia, Twitter, Amazon etc). On deleting the last one of the default ones, the 'Add a shortcut' button has completely disappeared. Is there another way to create a shortcut?

Video in Firefox does not run .. no error messages .. nothing. It works fine in other browsers. When I click on the video .. nothing happens. It used to work but not now and I don't think I've changed anything.

When trying to install any extensions on either the Mozilla Addons website or directly via the Extension settings, it fails to do so.

I've attached a screenshot of the Mozilla Addons website when it fails to install the extension. On some other addons that I've attempted in the past, it just shows the throbber forever.

I have checked the Multiprocess Browser Console and it says that it fails to move the file because it's locked (NS_ERROR_FILE_IS_LOCKED). I have also attached a screenshot of that.

I accidentally right clicked and hit "Remove from Address Bar" on the Reader View icon and now it's gone. I tried typing "about:config" into the browser and searching "reader" then selecting the "reader.parse-on-load.force-enabled" toggle to "true" and that didn't get it back. Is there a way I can get it back?

after creating a new profile, and copying everything in the root directory to the new profile, including search.json.mozlz4, the default search engine setting does not get transferred over and is still set to google

I often have many tabs open (25+) I have made it so tab shrink way more then normal (I like the way chrome handles tabs where they basically just shrink infinitely. Firefox doesn't do it's even with my twerks but ohwell.)

so when i want to click on a tab with audio playing at a small size i often mute the tab instead of clicking on the tab

Where and how can i remove the mute button that appears when hovering over tabs with audio playing?

I have never found that mute button useful so removing it will not impact me

Installed Firefox 122 in a new Windows 10 installation and added some extensions (e.g. Gesturefly, Update Scanner, uBlock Origin, Uppity). These pinned fine on my old installation. But I cannot find how to pin them on the new.

All the help I have found Googling, or using search here, says go to the Add-ons Manager page and right-click the extension and use "pin to toolbar". Alternatively click the extension and click the gear icon and use "pin to toolbar". But when I right-click there is no pin to toolbar context menu entry. If I left-click the gear I get "Check for Updates, View Recent Updates, Install Add-on From File, Debug Add-ons, Update Add-ons Automatically, Reset All Add-ons to Update Automatically, Manage Extension Shortcuts". If I right-click the gear I get a line of icons (left, right, reload, star) followed by "Open Image in New Tab, Copy Image Link, Email Image, Save Page As, Select All, View Pate Source, Inspect Accessibility Properties, Inspect (Q)". If I right-click the extension in the Add-ons Manager page itself, I get a very similar list. In no case is there a pin to toolbar option.

How do I pin an extension, given the above? What have I messed up?

When I press the pause button on my keyboard, it doesn't stop the YouTube video like it used to. I'm not sure why it stopped working. I've checked the key, and it works fine in Chrome.
