Firefox

Keeping open too many duplicate tabs? Me too. #Firefox Nightly now has an option in the tab overflow menu (that's the down arrow near the top right of the window) to close all duplicate tabs in the window.

For all duplicates, it's the last active tab that'll remain open.

Go reclaim that memory and CPU!

Finally duplicate tab management comes to Firefox natively.

Anyone know why?

I love the reader mode, it helps me stay sane, avoiding distractions and being able to use some heavy news sites on my low end devices. I wonder if there's a way to automatically open sites in the reader mode when it's available.

On Mobile (using Mull) the PDFs are completely pixelated and simply dont render more details. Even after zooming in it takes forever.

Meanwhile on Desktop (Librewolf, Firefox, ... on Fedora) it seems a bit slow compared to Okular, but it is very fine.

Didn't want to make title too long, sorry. By load back I mean read from clipboard or from a file or have an input box to paste from clipboard a lost of URLs and open each in a tab.

On my phone (it's a MIUI device) firefox sometimes acts weird, I can see URL in a tab but page looks empty. I can copy the URL manually, close the tab, open a new one, but this can be annoying if I have many tabs and this also changes the tab order.

Also, no, I can't just close firefox and open it again, as I mostly use firefox in private mode.

I just want to copy all open URLs, restart firefox, and open all my tabs in private mode again in the same order by pasting URLs back.

Also, android aften kills my firefox when it's in the backgroind without any warning.

Last time I searched, I couldn't find any such addons, but it's possible that I used wrong keywords.

I know this is Lemmy and plenty of users here are anti-Reddit, but I'm sharing this in case other users have trouble with this as well.

Edit: u/Capta1nT0ad commented a working regex rule, Idk why my attempts didn't. Anyway I modified the rule so it works only on Reddit u/ and r/ links, so it doesn't have a chance of touching links that aren't compatible. I made a pastebin for anyone that wants to just import the file.

A redirector addon is necessary to redirect Reddit pages from the new 2023-24 redesign to either the 2018 redesign or old Reddit*. Some pages can't be redirected, like https://www.reddit.com/prefs/feeds/ and https://www.reddit.com/mod/firefox/queue (the new mod queue, firefox being the subreddit name).

When I go those links, the following addons don't work for them: Reddit UI Redirector, Old Reddit Redirector, and Old New Reddit Redirector. New Reddit Redirect doesn't even work at all for me, though it hasn't been updated since 2019 and there doesn't seem to be a repo online, so its probably close sourced. I left reviews for all of them. The only addon I found working both links is UI Changer for Reddit.

* I tried making a regex rule with the Redirector addon but it didn't work.

When I click on a post in a twitter feed it opens it in the same tab when I want to open it in a new tab, and continue scrolling the feed.

• Firefox Relay
• Google Search Fixer
• YouTube High Definition
• OldLander
• uBlock Origin

The GitHub repo for Firefox History Merger was archived back in 2022, while it still works it might be a good idea for a newer alternative in case Firefox makes breaking changes in the future.

Do you know any Multi account containers addon alternative for android?

Anyone else experience this? I haven't ever had this problem with Chrome. Live streams on YouTube seem to freeze once an hour or so. Actually YouTube just seems way slower and much more laggy on FireFox. I am using uBlock Origin so maybe that is throttling things, but I'm not sure.

Any advice?

Dear @firefox : Please stop saving images as webp when I drag them out of the browser. Forever stop that. Even if they are webp originally, just give me a setting to auto-convert them to JPEG. When I get a webp file the first thing I have to do is convert it manually if I'm going to do *anything* with it.

Looking at the Mozilla logo, we could see a URI hiding (or not) in there. Like mysql://.

They should make it into a protocol like mysql here and incorporate 'a' in there then do something with it.

I would like to be able to perform the following actions from outside the browser, for example from a script

''' Obtain a list of all tabs, and which URL is open Obtain a list of all firefox windows and which tab is in each and in what order Obtain a list of firefox running instances Actions on tabs Close a tab Open a new tab and enter URL move a tab in a window's tab order move a tab to another window mute/unmute a tab make a tab hidden or unhide pin/unpin a tab select/unselect a tab discard a tab reload a tab copy tab body or a specific xpath run a javascript cmdlet, (bookmarklet ? ) Run a function of a script in somethingmonkey bookmarks list all bookmarks folder and bookmarks move a bookmark to another folder delete a bookmark create a bookmark get/change position of a firefox window close a window/ open a new window list installed addons turn an addon on or off '''

I would love to be able to write script, from outside firefox, and do these actions

I have found about the remote debugger, but I can't figure out if it's only for debugging firefox on android via adb ? Or can I use that directly from a script ?

https://firefox-source-docs.mozilla.org/devtools-user/about_colon_debugging/index.html#connecting-over-the-network

https://wiki.mozilla.org/Firefox_OS/Remote_Control

https://wiki.mozilla.org/Firefox/CommandLineOptions

devtools.debugger.remote-enabled -start-debugger-server ?

Is any of this possible ?

thanks !

To preface, I have had a thread about this previously,

https://kbin.social/m/[email protected]/t/840667/How-can-you-troubleshoot-a-crash-from-freezing

Ultimately, it didn't result in much.

Cue a few months, a lot has happened, and I have a new PC. Different graphics card vendor, different RAM, different motherboard vendor. Almost everything is different.

The crashes stopped, in fact I didn't notice them for a long time.

Past few days however, I noticed youtube videos starting to skip a bit. Thought it might just be youtube.

Then today happened. After about a month, I had a crash again. The PC has been left on for about a week (which is not really uncommon for me).

What I noticed that caught my eye...is that when i went to close it in task manager, it was using 14 GB. Just to be fair, I made sure before completing this post that I kicked every tab I had open out of inactive.

They are currently sitting at 5 GB.

What is occurring that is causing Firefox, under the same amount of active tabs (in fact possibly more, since I do have auto tab discard, so most of these tabs would not usually be active) to reach 3x the amount of ram they actually use?

I would like to get it to stop crashing, but it seems like even under a different hardware configuration, all I've done is make it take longer for it to actually happen, which makes me think even more that the it's an issue with memory.

I have no clue why, but i am not able to load http://feder8.me/p2pool/ on fennec 124.2.0 (android) but it loads fine on firefox focus 122.0, tor browser 13.0.12 (android based on firefox 115.9.0), and firefox desktop 125.0.2.

Can anybody else see if it's doing the same thing? Because I'm wondering if the desktop Firefox and the mobile Firefox are formatting in different ways when it retrieves the AAAA record from the DNS or something?

The picture above is one example out of many websites (that have drag n drop features enabled). I'm not actually dragging or dropping anything, which makes this very frustrating, especially as I can't get rid of the bug either. If I reload, it will just happen again and again. As mentioned, this happens on ALL websites, including messaging platforms. What on earth could cause this? Just started happening last week or so.

It's honestly driving me 🥜🌰
