Sorry ... hijack ...
Could you please implement a special:
settings://tabs
... URL that just gives a plaintext list of tab URLs currently open ?
As it stands, the only way to get this list is to poke around in /Library/ files and then use JSON command line tools to export ... etc., etc.
I just want a built-in page that gives me all the URLs of current tabs. I could then cut and paste them, or save the page, as I see fit.
1. Shift+Ctrl+D to bookmark all open tabs (in the current browser window) in a new bookmark folder.
2. Right-click on the new bookmark folder and select "Copy".
3. Then paste into your favorite text editor.
This isn't so much a feature request as it is a request for some simple debug info which can be accessed with a special://url (whatever those are called ...)
FWIW this sounds super easy to do within an extension: https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/Web...
It probably is but I feel like debug/info URLs are simple and lightweight and belong in the core feature set - especially this one which you can find hundreds of examples over decades of people asking how to get this information.
I actually never filed a bug report. I didn't think of the slowness as a bug per se. I thought it was just that Firefox was slower.
One thing I should note is that I've been using an ancient Firefox profile. I copy the profile onto new installs, and I've got bookmarks going all the way back to 2008 or 2009 (my bookmarks are organized into 50 or 100 folders). I also have a bunch of extensions.
I typically have well over a hundred tabs. I used to use the extension Tree Style Tabs, and sometime get close to a thousand tabs (with like 5 to 10 windows, with between 100 to 200 tabs per window).
Also, Firefox was slow on every laptop I used, but not on my desktop. I have a desktop that's fast by 2015 standards. It's got a i7-5280K, 32 GB RAM quad-channel, etc. The few laptops I've had have had far slower CPUs (the fastest one being an 8th Gen Intel i7 "U" processor). While on my desktop, I might average 700 tabs, on my laptop I try to have under 200 tabs.
I've always been on the newest versions of Firefox. For my laptops, I was on Aurora / the Developer Edition. On my desktop (which has an Ubuntu-based Linux distro), I'm on Firefox nightly.
Not sure if all of that info helps. I haven't investigated too much into what's happening. The most probably culprit might be my ancient Firefox profile. Perhaps, if I go back into Firefox with a fresh profile, it'll be a lot faster.
N.B. I'm currently a happy user of Brave as it has integrated AdBlock-style blocking, fingerprinting protection, and HTTPS Everywhere. I'm always evaluating my options as a user, though!
Google Docs performance is a long-standing issue, but it sounds like you're seeing an unusual problem. (I usually have 10-20 Google Docs tabs open all day in Firefox Nightly.) Perhaps try reproducing with any Firefox extensions disabled. Some, particularly ad blockers, can cause performance problems as they repeatedly scan the page's DOM.
So there might be a factor there. But perhaps it could be an add-on. I discovered that Lastpass injection feature to autofilled had a performance impact.
Switched to Bitwarden and it was noticibly faster.
Could you guys please add a feature where any link opened from within a container opens in the same container category? (Like if i'm in Personal, I stay in Personal unless I explictly opt-out)? It's such a pain to constantly right-click and open tabs. Thanks :)
Open the extension, click on 'Personal' and deselect 'Limit to designated sites'
PS: You can ctrl+click on the 'plus' button on the tab bar to open a new tab in the current container.
Try one of the many browser extensions that spoof Chrome useragent. For me it makes a big difference on Google search results and Youtube
I am replying only because I think your comment can be misleading to other readers of HN.
It's just that Firefox is noticeably slower than Chrome (or at least was about a year ago). Even simply switching between open tabs around what feels like 0.5 seconds, whereas on Chrome, tab switching is instantaneous. I've run Firefox in multi-process mode (since that was an option), but even with it, in general it seems like Firefox gets noticeably slower than Chrome when you have a lot of open tabs. I've always preferred and wanted to use Firefox over Chrome, but the performance degradation was too much to bear.
