As a user in China, since the domestic version of Firefox was discontinued, I switched to the international version. However, I’ve encountered a frustrating issue regarding how history entries open: When I click on a history entry in the **right-side history sidebar**, it **overwrites my current tab** by default. To open it in a new tab, I have to manually press the *Ctrl* key while clicking — which breaks my long-standing browsing habit. Previously, in the version I used (the domestic variant), a simple click on a history entry always opened it in a new tab. Strangely, the **left-side history panel** (if applicable) also opens history entries in new tabs without overwriting. This inconsistent behavior between the sidebar and other interfaces is confusing. I understand some users might prefer overwriting the current tab, but flexibility is key. Could Mozilla add a **configurable setting** (e.g., in *about:config* or the preferences menu) to let users choose: - Option 1: Overwrite the current tab when clicking history entries. - Option 2: Open history entries in a new tab by default. This would respect diverse user habits and resolve the mismatch between the sidebar and other history interfaces. Thank you for considering this improvement! 我是一个中国地区的用户，因为国内的停运了，现在更新了国际版的火狐，但是在用到国际版的火狐中，我遇到了这个问题：在当我点击历史记录时，会把我当前的标签页覆盖，如果需要不覆盖当前标签页，则需要我按住ctrl再点击。在这之前，我用的版本一直都是在新标签上打开历史网址的，然后我发现在左侧的历史记录这，点击历史记录则不会覆盖标签页，也是新打开一个标签。这让我很苦恼，我之前一直的习惯逻辑都是点开就可以了，而且是点开右边的历史记录侧边栏。我希望能够增加个设置什么的，可以给予用户选择的权利，如果有人希望点开历史覆盖当前页面，则覆盖，希望新打开标签页的则可以打开新标签页。谢谢

I want to view more tabs across the top and opened about:config > browser.tabs.tabMinWidth > and changed value to 75. For the rest of the session it worked. Opening a new session and the tab width is 100 again. Help?

For a week my pinned tabs are lost every time I open Firefox. I have checked my settings, they were the same as always. I have de-selected them, closed and re-opened firefox, selected them again, closed and re-opened again, pinned my tabs again. Then closed and re-opened firefox and still they are not there. I have done this multiple time with the same results. This seems to have started after the last update.

Firefox version : 141.0 (64-bit) in openSuse Tumbleweed.

This is a fresh install of everything because it's a new machine.

I used Firefox sync because we can't do the old thing of importing a pre-existing profile - it doesn't do what it says it should...

There are two behaviours in my old setup which no longer work, but which are related.

1. If I open a link in Thunderbird it should, if an instance of Firefox is already running, open in a new tab of the existing Firefox window. It doesn't. It opens a new window.

2. If I click on an external link to a site (ie one that points to another site) it should open in another tab. It doesn't.

I have tried the solutions suggested on this site and they don't work.

It used to be that if I clicked a link, the link would open a page next to the tab where I started. Now it opens the page somewhere remote from the start page and I have to search up and down the tabs to find the associated pages. Why? What is the fix? in the image, there is a yellowish heart shaped tab then off to your right is another. These are closer together and can be MUCH further apart.

I have Firefox configured with auto-expanding vertical tabs. Sometimes, when the mouse cursor leaves the Firefox window through the same border where the tab bar is located, the tab bar expands and stays in that state until the cursor returns to the Firefox window. This is especially annoying with two displays; if the cursor hovers over the tab bar right before moving to the second display, the tab bar remains expanded, overlapping part of the browser content.

I had an issue with v141 showing only pinned tabs but got that straightened out with a change to my userchrome.css file.

I noticed that double clicking the tab bar does nothing, but specifically, does not open a new tab.

browser.tabs.drawInTitlebar in about:config is set to true title bar in customization is checked

I have disabled a Tab Mix extension and confirmed that all pertinent about:config settings were set correctly but still I cannot double click to open a new tab.

Please advise. Thank you!

With latest Firefox Desktop 141.0 I found an odd behavior of pinned tabs which now are scrolling left and disappear from view site in a top tab bar.

• Is this a new feature or bug?
• Any setting to prevent them from scrolling?
• How to prevent this from happen?
