Firefox Jumps to Top of Page - No Apparent Reason

Post by EPAIII »

I use several bulletin boards that utilize various versions of the vBulletin software. Recently (past month?) I have found that as I scroll down the posts, just reading, not clicking on anything, the page will suddenly jump back to the top and I have to scroll down again. This can happen several times on a single page. It is very annoying. Is there anything I can do about it?

Firefox: 68.0.1 (64-bit). It reports that it is up to date. I have not intentionally installed any add-ins.

Though you state that you haven't installed any add-ons and if this problem happens pretty fast... you might want to try running Firefox in safe-mode to see if it still happens... that is normally the way to start figuring this stuff out...then post back here with your results.

Try running Firefox in safe-mode... NOTE: This is a testing procedure only ... NOT for normal browsing.
-- On the menu bar, click the Help menu and select Restart with Add-ons Disabled....
Firefox will start up with the Firefox Safe Mode dialog. Click continue in Safe Mode and don't check any items.

Note: You can also start Firefox in Safe Mode by holding down the shift key while Single/Double clicking on the icon.
* (option key while starting Firefox on Mac).

-----------------------------------------------------------------------------------------
>What safe-mode does ..... Safe Mode temporarily affects the following:
* All extensions are disabled. --- * The userChrome.css and userContent.css files are ignored.
* The default theme is used, without a persona. --- * The default toolbar layout is used.
* The Just-in-time (JIT) JavaScript compiler is disabled. --- * Hardware acceleration is disabled.

-- Safe Mode has no effect on the following --
* The status of plugins is not affected.
* Custom preferences are not affected.

This is the link to the main KB article for Safe-Mode ... but, use the above info 1st...

Also make sure that you haven't enabled caret browsing mode.
