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 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?

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!

I have Firefox set to "view PDF files in Firefox", but this is not happening with sites like Capital One and Consumer's Energy. these sites are just saving directly to my downloads folder even though I 1) Want to view the file first and 2) if it is going to save a flle, it is set up to ask where the file should be saved.

Neither of these things are happening even though I have them set up correctly in Settings.

Any advice returned by Google seems to be obsolete or only worked perhaps in older versions of Firefox. The main idea of using userChrome.css to override the default styles for Reader View does not seem to work. My userChrome.css file does work on other items though (like removing the sidebar width restriction).

Whatever advice I find via Google perhaps cites outdated CSS selectors, but current selectors do not seem to be documented anywhere by Mozilla. Moreover, I cannot find any file on my local drive named aboutReader.css when using find or grep commands in bash, those this file name is alluded to when viewing a page in Reader View and then in turn viewing source on that transformed page.

Moreover, addons that would allow me to change the colors seem to be restricted in Reader View.

It does seem like something has changed in recent Firefox updates but I can't remember when I last saw, for instance, links in dark mode Reader View that were still pink (whereas now they are blue, and impossibly dark to see, especially when you are disabling as much blue light as possible through your operating system). I need a higher contrast color for links in dark mode Reader View so I can actually see them.

I can alternatively use the Tranquility Reader addon and have custom colors, but A) that addon does not work with the Automatic Reader View addon, whereby I can always have various sites appear in some sort of "reader view" whether the native one or Tranquility Reader, and B) hitting refresh when in Reader View will defeat some soft paywalls but this does not work with, e.g., Tranquility Reader, so I still would prefer to be able to custom colors in the native Reader View feature, rather than rely on an addon.

1. Where are the current styles for Reader View even documented? 2. Is overriding them now restricted? 3. Why did the link color change from pink to blue in newer versions of Firefox (this is a terrible accessibility bug)? 4 .Where is the alluded to aboutReader.css stylesheet actually stored on my computer (it doesn't seem to be a file on the filesystem in the Firefox profiles folder, it seems more like it is embedded in the Firefox binary/executable)? 5. Will Firefox settings ever allow us to set colors specifically for Reader View (I don't mean the override settings for all web pages, particularly web pages not being rendered in Reader View ... that setting does not help in Reader View, nor would it be the desired preference for pages not in Reader View)?

Thank you.

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?

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

Hiya,

I use a theme which some years ago (after a change in the way Firefox handles dark-mode preferences) changed all UI and websites to use dark-mode. I was able to keep using the theme, and mostly override this behavior by setting:

`layout.css.prefers-color-scheme.content-override = 1`

However, this didn't take for some components, such as the sidebar and bookmark editor window, which still continue to use dark-mode.

Is there any way to completely disable dark-mode everywhere, and still use my preferred theme?

Cheers, Afraz

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.

When I download an image in Firefox and open it from the downloads folder it will always open in Pixelmator not Pixelmator Pro.

If I double click on an image file elsewhere they correctly open in Pro, but in Finder, the icons are for Pixelmator not Pixelmator Pro. This can be hidden if I turn on finder icon previews, but selecting Get Info always has the Pixelmator icon not the Pixelmator Pro one.

Im not sure if this is a macOS problem, a firefox issue or a Pixelmator bug but it seems to be related to the way the files are registered.

Things I have tried:

Changing file associations in firefox. Rebooting Changing the open-with properties in finder: Open all with Pixelmator Pro Reset the Local & User domains with lsregister lsregister -kill -r -domain local -domain user -domain system -v

When scrolling down I choose to read an article in a new window. When I open the new window, on the right side, a pop up window appears titled “Join the Conversation” or “More from Daily Express” blocking some of the article’s words. How can I stop this pop up window from appearing? Thanks.

I just updated to the latest version of Firefox, and all of a sudden I have a new icon, Extensions, that looks like a puzzle piece, I cant seem to be able to remove it....at all.

For the past few months every restart of Firefox disables LastPass. I did NOT have this problem previously. The version of LastPass is current (no updates found). I can go to Add-ons and the toggle is set to "on" but the icon in the menu bar is black. If I click the toggle off, then back on, LastPass comes on just fine. Why is Firefox disabling something that Add-ons says is loaded? VERY strange. Does NOT happen in Chrome. Thanks for any assistance. PITB!!!

Hi. I was just looking at Google Photos on both Firefox and Chrome. Chrome had a bigger picture because the window had only the tabs bar and the address bar, and Firefox has an additional title bar. I was wondering if it would be possible to remove the title bar so the picture on both browsers were the same size?

Firefox has started making a piercing high-pitched screech when the "save image" and "file update" panels appear. This is a confirmation or alert sound I suppose. It occurs when saving an image from a right-click menu and when downloading a file. Formerly Firefox used the system default sound for this, and that sound is still working in other programs for similar operations.

How can I fix this? Or alternatively how can I disable the sound during such operations in Firefox (or alternatively system-wide)?

Hello, in past versions of Firefox, I was able to follow the steps on this page to set a custom HTML file on my PC as my home page for new tabs: https://peterries.net/blog/firefox-ubuntu-local-file/

I have Firefox 107.0.1 now and it's not happening. When I open the browser from scratch, I see my custom home page file. But when I open a new tab, I just see a blank screen. If I then click the Home icon on the toolbar, I do see my custom HTML page, but I don't want to have to click that button for each new tab.

Right now, in my settings, I have the URL to the page set as the custom URL for the HTML fiile, like this:

file:///home/peter/Documents/homepage/peter-home-homepage.html

That works. And I also have followed the steps on that blog post to customize my /usr/lib/firefox/autoconfig.cfg and my ../firefox/defalults/pref/autoconfig.js files. That's no longer working.

Did something in a recent version change? Is this no longer supported? Thanks for any ideas!

Is there any way I can completely disable horizontal scrolling? I'm using a laptop with a trackpoint (lenovo x230, Windows 10) and it's not terribly accurate, which means scrolling whilst a youtube video is going often makes it track backwards or forwards, and another website I use uses a horizontal click to send me to the next page, which sucks. I would prefer to just be able to disable it entirely. Thanks!

I swear to god I used to have it disabled, just need to work out how again.

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.
