Left clicking link on Locked tab results in 2 new tabs and stealing focus (FF 127 Final)

[Insearchof18]

First time posting on github (just created my account lol), so apologies if I make any mistakes in reporting this issue! :)

After updating to Firefox 127, I started experiencing the above issue (tested on a system with 126.0.1 with latest TMP and everything's working perfectly). What was happening before the update with Locked tabs was that a single new tab would open with the resulting page and would not steal focus (middle-clicking a link still results in this correct behaviour).

To test, I installed a fresh copy of FF 127 (new profile) on a different machine that didn't have it (no other extensions installed), followed the instructions (https://onemen.github.io/tabmixplus-docs/other/installation/) from scratch to install TMP (tested with both the latest and the dev releases), and using the default TMP settings (without making any changes), I was able to replicate the issue. All tests done on Windows 10 x64 (22H2) systems.

Please let me know if any further info is needed for troubleshooting!

try the latest dev-build

• Provide an example to a page with this issue
• Any message in the Browser console?
• attach a file with you Tab Mix Plus preferences

hey @onemen, thank you so much for the speedy response (and appreciate all your hard work on this project over the years)! :)

The dev build that I tested with was the same one you linked (1.20.1-20240606.1715), so unfortunately that did not resolve.

• Clicking any of the links on the Installation page I provided above will result in what I mentioned, but really any site with any link (regardless of whether it has additional attributes, etc.).
• Sorry, not very familiar with using the console for troubleshooting, but if you can guide me on what info to get for you, I'd be happy to.
• As mentioned, the settings for TMP are all defaults (when I was testing). However, I've attached a copy of my prefs as well, which obviously results in the same issue.

@Insearchof18,

Thank you for the information.

I can reproduce this error with your preference. I will try to fix it tomorrow

[Insearchof18]

You're awesome, @onemen!! Thank you so much for your help!! :D

The issue is with the 'Links' preference above, when you enable it, the issue is gone.
I will investigate more tomorrow.

[Insearchof18]

You're a 100% right, I can confirm (both with my settings and clean install/profile/default settings for TMP)!

Great progress!! 👍🏽

Same problem,
not open Link Focus/ Lock this tabs→left click link→two tab & steal focus,
middle click→one tab & not steal focus,
if open Link Foucus setup left click→one tab,but i don't want steal focus.

This was a regression from commit ba7df31

Download and install the latest dev-build from today

Thank you so much, @onemen!! Works perfectly again!!

For anyone who was having the same issue and tries updating to the latest dev build but still has issues, I had to follow all of the steps from the installation instructions page (https://onemen.github.io/tabmixplus-docs/other/installation/) again before it started working properly for me (this was both on my main install and on my test machine with all defaults).
