User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:146.0) Gecko/20100101 Firefox/146.0

Steps to reproduce:

Opened a PDF with Firefox and started adding elements using the text and the drawing tool.

Actual results:

After a few switches between the text and the drawing tool, none of the tools buttons on the top right of the PDF viewer were clickable/selectable anymore. I couldn't find any particular action leading to this bug. I had to close and reopen the PDF file (without leaving the Firefox session) to make it work again. This bug occurred several times, on different PDF files.

Expected results:

All tools should continue to work.

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

Component: Untriaged → PDF Viewer

When it happens, could you open the dev tools console either with CTRL+SHIFT+K or in clicking on "Inspect" in the context menu ?
Then you should very likely see an error message displayed in the console, if it's the case could you copy and paste it here ?
