When using the Wayland backend for Firefox, a [https://gitlab.gnome.org/GNOME/gtk/issues/2112 known issue in GTK+] means that the {{key|Alt}} modifier key is still considered active in Firefox after you switch away from the window using the {{key|Alt|Tab}} shortcut. So if you then move the mouse over the inactive Firefox window (but do not click to activate it) and scroll the wheel, Firefox will treat this as holding down the {{key|Alt}} key and scrolling the wheel. By default, in Firefox, this is mapped to going 'back' and 'forward' in the page history, so instead of the page scrolling, you will rapidly move backwards or forwards through your page history.

If you find yourself frequently triggering this unwanted behaviour, you can work around it by navigating to {{code|about:preferences}} in Firefox and setting the value {{code|mousewheel.with_alt.action}} to 1 instead of 2. 1 sets the action when holding {{key|Alt}} and scrolling the wheel to be the same as when scrolling the wheel normally (it will scroll the page).

Pre-release version
Fedora 32 has not yet been released. During this pre-release period, this page will cover known issues in the Fedora 32 pre-releases. Issues that are fixed will be removed from the page once a fix is available (for instance, an issue that affects the Beta but is fixed in the final release will be removed at the time of that release).

Release Notes

Read the F32 Beta release announcement for specific information about changes in Fedora 32 and other general information.


My bug is not listed

Not every bug is listed in this page, but Bugzilla should be a comprehensive database of known bugs. This page is a sampling of the bugs most commonly discussed on our mailing lists and forums.

To see if your bug has already been reported, you can search Bugzilla. If it has not yet been reported, we encourage you to do so to help improve Fedora for yourself and others. A guide to Bugs and feature requests has been prepared to assist you.

If you believe an already-reported bug report should be added to this page because it is commonly encountered, you can:

  • Add it yourself, if you have wiki access. Common bugs instructions provides guidance on how to add an entry to the page correctly, but the most important thing is to make sure that the bug is listed - don't worry if you don't get the format quite right, we can clean it up later.
  • Or, add the CommonBugs keyword to the bug report. Someone from the QA team will then inspect the issue to determine whether the bug should be listed as a common bug. To expedite your request, please add a comment to the bug that includes
    1. a summary of the problem
    2. any known workarounds
    3. an assessment on the impact to Fedora users

For reference, you can query Bugzilla for bugs tagged CommonBugs:

  • CommonBugs? (bugs with CommonBugs keyword, but do not yet have a link to this page)
  • CommonBugs+(bugs with CommonBugs keyword and contain a link to this page)

Other software issues

Trying to scroll with mouse wheel in inactive Firefox window results in back/forward instead

link to this item - Bugzilla: #1650051

When using the Wayland backend for Firefox, a known issue in GTK+ means that the Alt modifier key is still considered active in Firefox after you switch away from the window using the Alt+Tab shortcut. So if you then move the mouse over the inactive Firefox window (but do not click to activate it) and scroll the wheel, Firefox will treat this as holding down the Alt key and scrolling the wheel. By default, in Firefox, this is mapped to going 'back' and 'forward' in the page history, so instead of the page scrolling, you will rapidly move backwards or forwards through your page history.

If you find yourself frequently triggering this unwanted behaviour, you can work around it by navigating to about:preferences in Firefox and setting the value mousewheel.with_alt.action to 1 instead of 2. 1 sets the action when holding Alt and scrolling the wheel to be the same as when scrolling the wheel normally (it will scroll the page).
