Textboxes used to create and edit webpages in a CMS (content management system).

There are two types textboxes: simple textboxes, only text can be put in: those boxes, I have no problem. Complex text boxes: text and media, pictures, embedded video etc. can be put in: abnormal behaviour of cursor keys and mouse. Describing the abnormal behaviour:

- cursor up key: act as "cursor home" - cursor down key: jump to end of article - delete key: jumps right over characters without deleting them, but encountering a (white) space:

  spaces, tabs and linefeeds are deleted.

- selecting text with mouse: nothing happen when clicking left, sweeping over text: nothing is highlighted.

Not sure when this starts, could be several days or few weeks. (current date: February 16, 2019) Could be related with last Java update.

Other browsers: Chrome, explorer and Edge: no problem.

Pls advice!

Is this a website, or a program on your computer?

Many site issues can be caused by corrupt cookies or cache.

Warning ! ! This will log you out of sites you're logged in to. You may also lose any settings for that website.

If there is still a problem, Start Firefox in Safe Mode {web link} by holding down the <Shift> (Mac=Options) key, and then starting Firefox.

A small dialog should appear. Click Start In Safe Mode (not Refresh). Did this help?

While you are in safe mode;

Try disabling graphics hardware acceleration in Firefox. Since this feature was added to Firefox it has gradually improved but there are still a few glitches.

How to disable Hardware Acceleration {web link}

Thank you very much FredMcD! I appreciate your time and effort...

I had done all those advices you gave, except de-selecting hardware acceleration. Anyway I did it again, clear cookies/cache. start in safe mode and disabling h/w acceleration. None of those clear the problem. Staying in safe mode the problem still exists. Two small adjustments on my early report:

- Using cursor down key, the cursor jumps to end of line (not end of article). And pressing up key: cursor jumps to beginning of the line. Still faulty behaviour. - I read in rich-text input box, in the right below corner: "powered by Tiny" So I expect the developers of this CMS system use a plug-in module from Tiny.

Answering your questions: - yes it is a webbased "content management system" to manage

 a website.

- cookies and cache cleared several times. - I have removed and reinstalled firefox completely. Did not help.

I put a screenshot of the face of the program.
