You have no idea how wide my smile was when I found this extension and started experimenting with it.

My workflow combines TreeStyleTabs, dozens of named virtual desktops, and Firefox's built in tab title searching ability. My tabs are an extension of my mind. But it's true! - I don't need 400+ tabs. The old ones just lose relevance after a while.

I configured a global limit of 200, waited for the extension to enforce it, and boom! my system's responsiveness jumped.

5 stars for what you have right now in v2.2.6 :)

I did run into a couple of issues, though, so I extracted your code and looked through it (pretty clean, thanks!) and I have a couple of comments:

1. I found a bug where the act of loading the preferences page causes the add-on to enter "current window limit" mode, regardless of whether it was configured to use "current window limit" or "global limit" mode until then. I think using a ?? rather than a || on line 141 of options.js fixes this.

2. The "Least Recently Used" strategy for removing a tab always removes tabs from the current window, regardless of whether the tab limit is enforced globally or per-window. This surprised me - I was expecting this strategy to remove the oldest tabs from all windows when the limit is being enforced globally. I admit both strategies are valid! My suggestion - split the current LRU strategy in two: "Least Recently Used (Current)" and "Least Recently Used (Global)".

3. I'm happy to see that the "last accessed" timestamp of a tab survives a browser restart! (I verified this!) If it did not, that would play hob with my setup. Just mentioning this here in case someone else was worried about it like I was.

I saw from another response that you don't have a repository anywhere, or I would have said all this in Issues or PRs or something.

I saw this is GPLv3 (thanks!) so I threw up a repo on GitHub with some changes. I'm not supposed to put links in reviews, but you can find it under user "mosbasik" and repo "limit-tabs". I've implemented the bugfix and LRU strategy split I mentioned.

Love the extensions, helps a lot with my ADHD! One thing that makes experience painful though is not being able to set sound volume - while the sounds are reasonable, often they are obnoxiously loud. In addition it's really painful when the app prevents opening it's own settings due to the limit, but it's really minor compared to lack of volume control.

Exactly what I was looking for. Thoughtfully designed. Many thanks, RudyF

Excellent addon, simple! The only issue I have is that it doesn't count pinned tabs.

Does what proposes to do

Great addon, does what it says on the tin! Very similar situation for me with my sister, tons of tabs and she would complain why her laptop would be slow, was able to deploy the plugin over group policy to prevent removal and it works a treat!

Excellent add-on! Gets the job done!

Simple but effective, not trying to be more than it needs to be! Helps my (possibly autistic and/or ADHD) butt

I couldn't live without this extension now! I always open new tabs because I'm generally working on something and moving back and forth. Things can grind to a halt real quick. This way my 10 most recent tabs stay alive and the old ones just disappear. It's perfect. The only thing that bothers me is the icon - are you angry with your son?! It bothers me a bit. But the extension is brilliant.

Very useful extension! Thanks.
On Linux Manjaro, where the sounds (Gong, Buzzer, etc.) are stored? I searched in my FF profile, but I can't find them.

Unfortunately, I can't hear the sound alerts when a tab is closed (but I can hear them when I select them from the Limit Tabs' "Preferences page" on FF Add-ons Manager.
Linux Manjaro KDE.

Looking forward to trying this more. Just barely installed it and checked out and adjusted the Options(thanks) and it seems awesome so far! Thank you for doing this!! P.S. is there a site where i can look at the code for this extension and get notified of changes/commits?

Awesome except.... for the annoying sound when trying to open an extra tab! You really should make it customizable so I can pick a gentler sound. Otherwise it's great - thank you for sharing it.

Hello! I suggested implemmenting one tab limit some time ago, but I realized how unpractical that is. I had another idea though: scheduling the tab limit to certain times of the day, so you can for example only limit your tabs during work hours. Also maybe there could be an option to, during the time scheduled, disable the possibility to toggle the extension through the icon. Just throwing in some ideas, don't even know if it's doable or simple to do, but the extension is already excelent as it is, thank you!

Exactly what I needed, works great - and it appears to be the only extension in the store that does exactly that. Excellent.

This is an excellent plugin for anyone who struggles to self-regulate their browsing. One request to make this extension even better - Is there a way to count pinned tabs towards the total number of open tabs?

Awesome add-on! Thank you for making this. I have a bad habit of opening an absurd amount of tabs, so this will help keep me in check.

Excellent! Thankyou Rudy!
