Firefox Community Forum

Hello,

I have old 15 year old mac el capitan -10.11.r with outdated firefox 78.15.0esr 64-bit.... in perfect condition. Unfortunately I can not make updates on browser anymore. Online banking websites does not allow me to use this outdated browser. Would you be so kind to make even paid update for me? Or at least let me know what settings I should change under about:config

Waiting to hear from you! [edited email from public]

Changing Default Behavior (CSS)

When I'm reading on a computer screen, I hatehatehatedespisehatehatehate "widow and orphan" control. This is especially annoying when reading a long narrative passage that reflows so that a break (often a blank paragraph) falls at the bottom or top of a column/page. There are two relevant CSS properties, each taking a nonzero positive integer as an argument:

    widows: [number of lines]
    orphans: [number of lines]

It appears that Firefox has (like most browsers) established a "default" value of 2 in each of these parameters, which seldom appear in site-specific stylesheets. Do Not Want.

Is there a way to change this default behavior to the equivalent of:

    body {
         widows: 1;
         orphans: 1;}

without either (a) breaking anything or (b) having to redo whatever change every time there's a Firefox update?

Steps to recreate:

1. Open any website
2. Make any css changes. These will be shown in the Changes tab in the dev tools
3. Close dev tools, then re-open. Now those changes won't be shown

Sometimes I need to close dev tools in order to see how the web page would look normally.

Hello,

as per description I noticed that firefox version 138 requires an ArrayBuffer as the argument of WebAssembly.compile() and doesn't allow anymore (like in 137) a SharedArrayBuffer, is this intended or it will be fixed in the future? Follows a simple test case. Kind reagards.

--- index.html --- <title>Example</title> <button onclick="testWasm()">Press to run wasm function (sum)</button> --- ---

--- sum.wat --- (to convert into .wasm using: wat2wasm sum.wat -o sum.wasm) (module (func $add (param $lhs i32) (param $rhs i32) (result i32) local.get $lhs local.get $rhs i32.add) (export "add" (func $add)) ) --- ---

I asked this question two years ago and the chosen solution no longer works for newer versions of Firefox. (135 in my case) . setting editor.use_div_for_default_newlines in about:config to FALSE does not work.

I am tired of pressing SHIFT <enter> to get <　br　> . Unnessessary <　div　>s make code harder to read.

Any new setting I could use to get
for pressing the enter key?

Hello!

I would like to dump Chrome and return to using Firefox. I just would like to know if it's possible somehow to remove about:mozilla page from within a browser (it's important for me). If anyone knows of a way to do it - please let me know.

Thank you!

This button that looks like a jig saw bit will not budge.

Can I delete this in about:config by deleting the 'unified extention button' and can I delete the 'HKLM/SOFTWARE/Wow6432Node/Mozilla/Firefox/Extensions' in the registry?

Firefox these days is getting a burden with more info and such like being collected behind out backs, it's about to be ditched on all my computers, the last few episodes make me want out.

I have to manually change the layout.css.devPixelsPerPx setting evertime I switch from my laptop to an external monitor. What can I do to avoid this every single time?

Steps to reproduce- (1) Enable 'accessibility.blockautorefresh' in 'about:config' (This is said to ask for permission before redirecting) (2) Go here (3) End up here without permission

Extensions I'm using- Privacy Badger, uBlock origin, clearURLs and Show/hide passwords

Another question, does enabling this setting also stop internal redirection?

Is there a way to make the URL high lighting of the domain more obvious? I find that most people can barely see the highlighting and I'd like to make it obvious (bolder and red, or highlighted in yellow, for instance.)

Can this be done via userchrome.css?

Thanks,

Thane

After typing in about:config and clicking on the 3 lines top r.h. corner I'm supposed to get a page that list preferences. (using Wndows 11) That page does not appear. I wish to change my value for width scrollbar width from zero to 4. I have also accessed videos - with sound -but find i very hard to follow the voice of the presenter because he/she talks far too fast, and in many instances is outdated! I need a page on screen that tells me to type in specific keystroke to get to the page that lists a preference I can change.

Hi Firefoxians,

I need to ask regardining this security.cert_pinning.enforcement_level. how can i set this value using the windwos server GPO? i could not find this even after copying the firefox.admx file. could someone please guide me how can i acheive it?

I would really appreciate the help!

Regards Sheras

I have tried every support advice I can find and no matter what I do passwords are not restoring. Here is what I have done: Opened about:profiles Opened profile folder Exit firefox transfer key4.db and signons.jstor files from backup to the new folder

Nothing happens.

I have tried creating new folders and following those steps. I have tried everything.

Hello,

I have an issue where, when I switch tabs with Ctrl+Tab, my mouse cursor accidentally triggers something if it happens to be in the center. This is very annoying. I tried Googling how to turn off tab visualization through the config, but it hasn't worked so far.

   * browser.ctrlTab.previews

• browser.tabs.closeWindowWithLastTab
• browser.tabs.animate
• toolkit.cosmeticAnimations.enabled

So now, the only option I see is to turn off Recent Tabs, but then the browser becomes unusable. I also tried the same on a new clean user profile and even on new Mozilla-based browsers, but still nothing. It would be ideal to make the cursor inactive while switching tabs, like it is in Arc Browser and probably many others. But I would be happy enough to just turn off tab switching visualization.
