Firefox Community Forum

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.

How do I turn off web translation permanently for ALL pages in Firefox 118.0.1?? It´s the most annoying feature so far from Firefox. Even if I delete all languages in preferences, it shows up on every page I visit.

Hello everyone,

to archieve some good old games, I use an special version of Firefox. Firefox (MyPal): 29.2.0, with Adobe Flash preinstalled, Disk-Cache

For most games it will suffice: After loading all content online, it will be available offline too. But... some audio/video files will be saved in memory cache - %temp%\mozilla-temp-files\*[random-auffix] - instead of in disk cache. After closing session they get deleted and after restart they are saved again, with another suffix.

Sample file: http://arcaneonlinegame.epizy.com/Arcane/frames_files/midi/Ophelia's Journal.mp3 that is shipped with http://arcaneonlinegame.epizy.com/Arcane/Arcane.htm

How can I tell Firefox to permanent save streamed audio/video files, like Firefox does with everything else? In the end the music should play if I open the browser offline too.

Thank you in advance for your help. Drago

Hi.

How come there is no option to turn off "Firefox Translation"? I speak three languages and every time I visit foreign web site, Firefox suggest translation to me. It's annoying.

Every time I go to Fox News, the video at the top of the page drops to the lower right-hand corner. It's an annoyance I've been searching for a way to eliminate. I have pop-ups blocked in preferences and I have a couple of different pop-up blockers, but nothing seems to work. I'm currently using Firefox 114b.09 on a Mac Desktop.

My elderly mother has twice (in the last month alone!) been scammed by selecting the first thing that comes along in a Google search. I realize this is simply never going to change, and I need to take steps to prevent her from ever seeing any sponsored results of any kind, or any kind of address bar autocomplete suggestion.

I have taken several dozen hours of my personal time this past month to repair the damage from her first scam experience (that I know about!), and today's incident made me realize that I have to do much more customization of her browser than I previously imagined. When I told her to never fully trust a Google search, her reply was "but I used Firefox!", and that told me everything I needed to know. It simply cannot be left to her understanding of the internet.

The intended setup is an iPad and a Win11 laptop. I would like to set up Firefox so that the address bar is nothing but an address bar without any kind of autocomplete at all. Is this even possible?

Also, I obviously can't filter every scam known to man, but I would like to specifically block the kind of pop-ups and ads that scammers use. What is a good strategy for this specific purpose? I don't care about legitimate marketing ads, even though they're annoying to me personally.

The mute icon only shows on hover and takes up 50% of the tab size so I'm constantly accidentally muting tabs without realizing it and silencing video calls and the like. The top Google result for this issue -- rightfully yelled in all caps because this is an absolutely horrid UX -- says to set browser.tabs.showAudioPlayingIcon to false, but that does absolutely nothing in FF 100.0

How do I get the + sign back on my tabs? After latest update I can only close tabs instead of opening new tab, and I am talking about after opening several tabs. When I have seven tab open, I have to do ctrl+t to open new tab instead of just clicking on the + sign that use to be at end of tabs. Yes, I do use custom settings. This happened before but I was able to fix by going to tabs under about:config, but it seems the setting is no longer there.

After updating to version 121, the cursor theme, while having it on the window, changes from the default one (Breeze) to Adwaita while also getting like 2x bigger. How do I change it back to default theme and size?

Hello!

I have been using this userChrome.css code to hide the tab bar if there is only one tab (on Windows):

tab:only-of-type, tab:only-of-type + #tabs-newtab-button {

   display: none !important;

}

#tabbrowser-tabs, #tabbrowser-arrowscrollbox, #tabbrowser-tabs > .tabbrowser-arrowscrollbox {
   min-height: 0 !important;

}

Since one of the recent Firefox updates, this code does no longer work. Maybe because there is a new element in the tab bar: A drop-down list at the right.

Any idea how to make the above code work again?

in the firefox browser is there any way to see the casting the browser screen to chromecast on tv. similar to 'cast to media device' in edge browser or chrome browser.

After the latest update (124.0.2), two of my add-ons (Tapermonkey and Youtube Redux) are not working, even though Firefox says they're enabled, and it is giving no indication that the add-ons aren't working, no pop-ups to enable some permission for these extensions. Both of them reformat the layout of websites to make them more usable, and using sites without them is basically impossible for me. I have tried:

• Restarting Firefox
• Disabling the add-ons, refreshing, enabling the add-ons, and refreshing again
• Checking for add-on updates (everything is updated)
• Deleting and reinstalling the add-ons
• Restarting my computer
• Checking the permissions in the extension menu
• Turning off all other extensions except for one of the ones with issues
• Reading through the FAQs and help pages and following the instructions on some of them

Nothing has worked. Every time I reload one of the sites affected by this to check if it's finally worked, the site takes a very long time to load. Since these add-ons are for different websites and both aren't working, I know that the problem is not with the sites themselves. Thank you.

I have the following settings in Settings/Preferences>General:

Files and Applications

Downloads Save all files in the following folder: Downloads Ticked Ask every time where to save a file

Applications Portable Document Format (PDF): Open in Firefox How should Firefox deal with other files? Ticked Ask whether to open or save files

On specific websites when I click on a pdf link, Firefox opens and automatically saves the file to Downloads folder without asking whether to save and where to save despite the above settings. As far as I remember, on other websites when clicking a pdf link Firefox only opens the corresponding file and doesn't save.

I found this with a internet search https://connect.mozilla.org/t5/discussions/stop-saving-pdfs-to-downloads-when-viewing-in-firefox/td-p/10225.

How can it be disabled that Firefox automatically saves PDFs?

In the about:profiles page I can see that the Root Directory for my current profile is: /home/username/.mozilla/firefox/no9r1iq5.default-release-1681391696978 When I click the Open Directory button it does nothing. When I manually navigate to /home/username/.mozilla/firefox I can see that there is no folder there called no9r1iq5.default-release-1681391696978

The Local Directory is show as: /home/username/.var/app/org.mozilla.firefox/cache/mozilla/firefox/no9r1iq5.default-release-1681391696978 This exits and opens with the Open Directory button.

If I search for no9r1iq5.default-release-1681391696978 in the file manager, I see that there are two folders with this name, on at the Local Directory path shown above and the other at: /home/username/.var/app/org.mozilla.firefox/.mozilla/firefox My assumption is that this is actually the Local Folder (it contains files with today's date)

My question is, why does about:profiles show the wrong path for the Local Directory or why is the actual Local Directory in the wrong place (it appears that the path shown in about:profiles is the normal default location)?

I tried creating a new profile and it was created in exactly the same way: the Local directory path is: /home/username/.var/app/org.mozilla.firefox/.mozilla/firefox but about:profiles says it is: /home/username/.mozilla/firefox

I would rather have my profile in the normal default location but I want to ensure that I don't leave pointers to the wrong location that could cause problems.

I am running Firefox 121.0 (64-bit) from flathub on Debian GNU/Linux 12 (bookworm).

Any help appreciated.

I have used Firefox for years. I am computer literate and do not like the newer approach Firefox has taken to save all downloads to my downloads folder. I have to continually go in and manually delete the files.

For instance, I have a lot of pdf forms that I have to open directly in Acrobat, those files are then duplicated and saved in my downloads. This is causing a mess for me.

This was NOT an improvement in my opinion. Is there a way to stop this???

One quality of life thing I really miss after switching from Chrome is the option to "Goto ip" when you highlight and right click on a local ip address.

I do a lot or networking and am going to local ip addresses all the time (ie 192.168.1.1 or 10.0.20.15). When I highlight an address in the local ranges in Chrome it gives the "Goto" option, but Firefox always offers "Search Google for"

I really miss this option and unfortunately all my searching has not yield a solution since search engines cant quite make sense of my requests.

Hopefully someone here can nail something down.

Thanks!

Hello,

We are adding accessibility features to the Emmabuntüs Debian Edition 5 Linux distribution based on Debian 12, and we would like to use the reading mode included in Firefox to enable smoother voice reading for visually impaired people.

Currently we are going to use the Svox Pico and eSpeak speech synthesis at the same time because in SVox Pico we do not have all the voices we need for our possible users, particularly Portuguese.

We have found how to make the synthesis used by Firefox's reading mode be SVox Pico by default instead of eSpeak, however this requires a modification in the /etc/speech-dispatcher/speechd.conf file.

To do this, simply put the default pico synthesis in this file:

DefaultModule pico

But this causes problems with other software that we intend to use.

We found how to make all the voices of a speech synthesis appear in the Firefox playback menu by going to about:config and doing a search for the word "narrate":

Option narrate

On the other hand, we cannot find how to modify the "narrate.voice" option to tell it to default to pico speech synthesis instead of eSpeak synthesis which is the first synthesis loaded by speech-dispatcher, because we must keep eSpeak as the first synthesis loaded and do not put a default synthesis in speechd.conf to maintain compatibility with software that we wish to use.

Do you have any tips or a manual that explains the possible options for the "narrate.voice" option?

Thanks in advance for your help.

How can I disable the ctrl+t shortcut? I have tried using the Shortkey add-on, but it will not touch the ctrl+t shortcut. It works for everything else, just not that one. I've been told I can modify the browser.xhtml file inside the omni.ja file, but I am finding that almost impossible. Has anyone managed to do this?
