Sometimes I can bring them back by opening a new tab and immediately closing it. Sometimes not. Reproducible: Sometimes Steps to Reproduce: 1. Set the option to have the close button on every tab 2. Have many tabs 3. Keep an eye on the close buttons of inactive tabs while doing your browsing Actual Results: Sometimes the close buttons on inactive tabs disappear Expected Results: They shouldn't
Mozilla/5.0 (X11; Linux i686; rv:2.0b12pre) Gecko/20110221 Firefox/4.0b12pre Setting bug to New, considering what is written here: http://kb.mozillazine.org/Browser.tabs.closeButtons Although, I am not sure if this setting isn't overwritten when more than 9 tabs are opened.
I believe this is intended when we display the scroll arrows and too many tabs are open.
A way to override this would be nice. Because that's exactly when I have many tabs I miss the close buttons most.
Please, don't just close. Ok, it may be not a bug (since the annoying behavior seem to be documented). But it would be a nice enhancement to be able to override the behavior (10 tabs! Where on the earth have you this number?!) I cannot reopen the bug this one is duplicate of, but if I don't, I'm sure the issue will be just ignored for ever.
You can override the behavior by modifying the browser.tabs.tabClipWidth preference.
No, I can't. The default value is 140 (yet another senseless constant?), and no matter to what I set it (1, or 200), the close buttons disappear.
Don't reopen this bug again. The preference isn't live. If you have further questions, please ask them in the appropriate forum.
Ok, for people who don't belong to mozilla elite: "preference isn't live" should mean "restart the browser after changing". Besides, the (senseless) value of preference browser.tabs.tabClipWidth means minimal width the first non-pinned tab can have before tab bar starts loosing close buttons. If the "first non-pinned tab" gets any narrower, the close buttons disappear. Setting the preference to 0 restores the close buttons according to closeButtons setting. For the interested, try looking through this: browser/base/content/tabbrowser.xml, search for "adjustTabstrip". So yes, I agree, that reopening bug is not needed. I also note for myself and anyone who cares to read this comment this far that this particular mozilla developer was an unpleasant source of information in somewhat open-ended form.
