Firefox Community Forum

So I wanted to read PDFs trough firefox with a dark theme, looked up how to do so online, and people say to change the "about:config" option "pdfjs.viewerCssTheme" to "2" instead of "0", I did that, tried opening a PDF, nothing happend, it was still black text on white backgrounds. Tried closing firefox, reopened the pdf, nothing happened, still white backgrounds. Tried to check if it might have to do with that specific pdf file's config, created my own PDF file from a word document, tried to open it, still white backgrounds. Tried disabling extensions, (which I use four of, UBlock Origin, SponsporBlock, Return Youtube Dislike and Translate this page), didn't work. Tried enabling the option on my laptop, didn't work. Tried a bunch of other stuff and it still won't work. My Firefox version is 109 and I'm using Windows 10 I also don't want to use the console/file edit thing with grayscale(1) invertcolor(1) or whatever it was since it also reverses the colors of images instead of just the backgrounda nd text color.

I've disabled this for my google account. So when I search from google.com this behavior doesn't happen. But when I type anything into my address bar on Firefox to search, the first suggestions are from my search history.

I don't want to delete my search history.

I often use my search history to find specific things that I need, but didn't bookmark at the time. I need my search history to be saved. I just don't want to automatically receive suggestions based on it.

Is there any way to turn this off? Even with an extension or something?

Hi,

I'm using FF on Fedora 39.

However Firefox does not remember any file associations. The MimeTypes.rdf file in the profile is missing and is also not created on restarting the browser.

In the options I've now set the configuration to "Ask whether to open or save files". Now I see a popup when clicking on a file however there is no checkbox with "remember this file associations" (or something similiar).

Hello

Since an update from a few days ago (May 2024), my address bar/search bar is now basically outside of my PC screen, see here: https://vimeo.com/948314161

It's not a local problem, it's also happening on other PCs/Laptops I have.

How can I fix this? PS should the answer be that I need an add-on or anything like that, then it's bye bye Firefox, hello Chrome

Thank you

I'd like to be able to open a link in private mode by holding down some modifier key, then clicking on the link. There are many times that I want to open a link in private mode, and a keypress + click would be the quickest way to do it given that one hand typically remains at the keyboard while I use the mouse/trackpad.

I've even added a toolbar button to open a new private browsing window, then dragged and dropped a link onto the button, but that gets a circle with slash icon and nothing more.

Others have asked this question, so, to be clear, none of the following address my question: copying the link then opening the private browsing window & pasting the link, using a customized shortcut/bookmark, opening Firefox in private mode via command line, right-clicking the link then selecting "Open link in new private window".

Thanks for any advice and thank you, Mozilla, for Firefox!

When I search directly from the address bar, the search always defaults to google.com/....whatever I am searching for. But even though my region is set to United Kingdom, my search results are definitely not the same as if I were to navigate to www.google.co.uk and then search for the same string. Is there any way for the default google search to use google.co.uk rather than google.com Thanks?

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.

Is it possible to spell check the entire web page using both Hunspell built-in dictionaries and user-defined dictionaries *.dic, already prepared text in Firefox. As it is done in text editors like Libre Office (also uses Hunspell) but for web site, checking the text from top to bottom with errors in a separate window, so spell check is not only in the text input/search field.

I accidentally pressed a lot of keys on my keyboard and for some reason the default colors of Firefox have changed. I found out that by using Ctrl+Alt+D that I can switch the colors back to normal or to the colors that now appear automatically, but this only works for one tab. If I open a new tab, it shows the weird colors (see images below). I tried looking up specific shortcuts for Firefox considering the shortcut mentioned before (Ctrl+Alt+D) only works on Firefox. But I can't find any shortcut tied to that combination. I'm unsure what to do and how to fix this.

I would appreciate it if someone could tell me how to fix this.

Good day, has anybody an idea if and what addon could manage for me redefinition of mouse behaviour. Particularly in my case I want to use middle (wheel) button single click over any text input to perform clipboard paste (but everywhere else the button behaves normally). I had this feature integrated into mouse gestures add on which is no more compatible.

After applied Chinese Language Pack, the menu didn't change ,even after restart firefox or the system. I tried refresh firefox and re-install the language pack, the same situation appeared.

using firefox 115.10.0esr (64-bit)

I want to disable this redundant dropdown there is a post here from 6 years, but dont dolve my problem, I dont want to disable or separate the seach and the url bar, i just want to get ridoof this redundant information, just for curiosity, if i disable search or separate the bars, i still get the anoing dropdown but with "Visit" instead of "Seach with"

Hello

There seems to be a new function that opens a quick search window when I press the apostrophe key. This function is active on many websites, and I am using Firefox 125.0.3 on a Macbook Air.

This new function makes it very difficult for me to practice touch typing in Firefox, and I would like to turn this function of.

Best regards Max Andersson

Starting with Firefox version 120, you can set Firefox to automatically launch whenever you start or restart your Windows computer. https://support.mozilla.org/en-US/kb/open-firefox-automatically-when-you-start-computer

The browser shows opt-in prompt for the user to easily setup this behavior. However, I do not want to do this.

When I click "No thanks", the prompt goes away, but couple days later, it returns. I guess that an update resets the prompt status.

Is there a way to permanently disable this opt-in prompt without allowing Firefox to start automatically with the computer?

With previous versions of Firefox (before 108.0.1) I was able to make changes with about:config to allow a default domain id .com to be added to my Internet query. Example I enter cnn and would get cnn.com and assess the website. WIth 108.0.1 I enter cnn and Firefox cannot find the site. The about:config changes I made are:

 set browser.urlbar.autofill to false, set keyword.enabled to false and set browser.fixup.alternate.enabled to true. 

The changes are mentioned in the incident https://support.mozilla.org/en-US/questions/1142103.

With 108.0.1 how can this be implemented like in the past versions? Thanks

In previous versions I was able to open around 15-20 tabs before X button disappeared from them and I was no longer able to close them without activating them first.

Now this happens much earlier - only 10 tabs is enough on my 1080p 100% scaling desktop and 9 tabs on my 1080p 125% notebook.

X button is present if you have 10 tabs or less, but disappears with 11 tabs, when there is still plenty of space on tabs to click on X!

I compared it to brave and in brave you can still have 22 tabs opened before X button disappears!

Anyone has any method to force presence of x button? This is really annoying as I often have much tabs open and close only 2-3 of them. Now I have to open each one again to be able to close it.

Just updated a friend's computer from Windows 7 to 10. Installed firefox over previous ESR and now there's no way to remove the search bar from the new tab page. On my W10 system, the search bar isn't there, not sure how or why, but on her's there's no option NOT to show it as there used to be.

I found some VERY old (2014) info on this but doesn't seem to be up to date.

PLEASE give us our options back and stop taking them away, sheesh, getting as bad as Microsoft.

Is there a workaround for this to remove the redundant search bar from the new tab page since you can search from the address bar?

Thanks!

I am attempting to copy values from one google sheet to another and am unable to do so effectively as whenever I press crtl +shift + c I open the the developer tools. All my efforts on looking for a solution have lead me to unsupported extensions so I'm stuck wondering what to do.
