In response to a proposed solution from willjoe24421 on Jul 12, 2023, 4:49:40 PM ("Once you arrive on a web page, press and hold the Ctrl key and move your mouse wheel up to increase font size. To decrease font size, press and hold the Ctrl key, and move your mouse wheel down to reduce font size. Press Ctrl + 0 to return to the default font size. Regards, Will"):

I should have been clearer, this is Firefox Mobile for Android. So I don't have a ctrl key nor a mouse wheel. Any other ideas?

Hi

To help us to look into this further, please can you type about:support in the address bar and select the Copy raw data to clipboard button at the top of the page (you may need to zoom in to see that button). Please can you then paste the results in a reply to this thread.

If possible could you also install Firefox for Android Nightly from the Google Play store (it will not alter the data stored in the Release version - that will stay there). Type about:config into the address bar and search for the gfx.webrender.software preference. Use the controls to change that to true and try the website you were trying to use before again. Does this is now work?

WARNING from the moderator team: Changing Firefox preferences from the about:config page can sometimes break Firefox or cause strange behavior. You should only do this if you know what you're doing. Please read Firefox Advanced Customization and Configuration Options to learn more.
