1964500 - Some buttons stop working after a certain time

Status: RESOLVED WORKSFORME

(Core :: Widget: Gtk, defect)

Description

[rashid_usm]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:138.0) Gecko/20100101 Firefox/138.0

Steps to reproduce:

I started Firefox and used it for more than two hours, creating less than ten tabs in the process.

I am using Firefox on Fedora Linux 42 with the KDE Plasma desktop. Fedora is completely up to date. I have only noticed this behavior since updating from Fedora 40 to Fedora 42.

Actual results:

Certain buttons stop working, while others still work.
These buttons have stopped working:

• The "close window" button on every tab. When I hover over the button, the "x" is highlighted, but clicking on it has no visible effect.
• Almost all buttons which sit to the left and right of the address bar, e.g. "page back", "page ahead", "reload page", "options", "print", ... Hovering over them does not highlight them and clicking them has no visible effect.
• The address bar itself. Clicking on it has no visible effect (e.g. no cursor shows up) and typing after clicking on it also has no effect. One exception: If I open a new empty tab, the cursor is already visible in the address bar and typing an address and hitting enter loads the page. After that, I can no longer access the address bar in this tab.

Only the "home" button still works. It is highlighted when the mouse hovers over it and clicking it loads my home page.

The right-click context menu for every tab still works and I can close a window using "close tab" there.

The right-click context menu on the page itself also works and I can use the "page back", "page ahead" and "reload page" buttons in the context menu.

Expected results:

All buttons and the address bar should still work.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Does CTRL+L work? Or, it is also broken.

CTRL-L still works. The cursor blinks inside the address bar, I can enter text and if I hit return, Firefox loads the requested web page.

Also seeing this on Fedora 41. I can't reliably reproduce it.

I just want to note that the issue seems to have resolved itself for me. I have not seen the issue in several weeks. Before that, the issue had happened reliably after about an hour. My current Firefox version is 141.0, updated via the Fedora automatic update process.

Okay, Thanks.
