Foxit PDF reader crashed when try to comment or highlight text

Foxit reader closed when I try to highlight text (open highlights, write comment, etc) in any PDF file.

Reinstall does not fix the problem. (The Foxit-reader version is: FoxitReader.enu.setup.2.4.1.0609(r08f07f8).x64.run )

the log error in /var/log/syslog/apport.log file is

ERROR: apport (pid 20609) Sun Jan 21 15:37:40 2018: executable: /home/mostafa/opt/foxit/foxitreader/FoxitReader (command line "/home/mostafa/opt/foxit/foxitreader/FoxitReader")
ERROR: apport (pid 20609) Sun Jan 21 15:37:40 2018: executable does not belong to a package, ignoring

Is there any way to find the problem and solve it?

Thanks for any help.

• for first comment

  1. Difference of highlighted text showed in Evince (Right in figure) vs other PDF readers (here is Adobe reader) Fig: Evince vs Adobe reader

  2. Foxit reader shows texts better than other at least adobe reader and evince. Fig: evince vs Foxit reader for reading some text (also, you can test this PDF file from here. )

After helps of Foxit Reader's technical team. the solution is founded. It seems the problem was occured after updating the language packages (from language support of Ubuntu system setting).

The solution: Going to ‍/home/mostafa/.local/share/Foxit Software/ address (use your home name instead of mostafa), and deleting the "Foxit Reader" folder. Then, if needed, reinstall the Foxit reader.

Also, if you needed to saving the log file, it is the way from Foxit Reader's technical team: .... "Please open Foxit Reader, go to Help>About Foxit Reader, click on Foxit Reader text three times continueslly, you will get the directory for saving the log file." (notice: I clicked multiple times on it, to this open)

I am appreciative of Lyndi Wu from teckincal taem and @Lynob.

One possible solution is to disable internet related functions, including

1. "Connected PDF" :

Edit -> Preferences -> General -> Disable Connected PDF features

2. AutoUpdate:

Edit -> Preferences -> Updater -> Do not check for updates

One of the posts on their online forum seems to point to connected PDF, and foxitdrive etc.

It's just a guess, but disabling the above seems to work so far.

Also, according the Foxit, current support for Linux is up to 16.10:

Our existing version of Foxit Reader for Linux's OS requirements are as follows:

Ubuntu Desktop 14.04 ~ 16.10

Red Hat Enterprise Linux Server 6.x (64-bit) ~ 7.x

...

So it doesn't support Ubuntu 20.04.

In addition,due to human resources limited,our developers have stopped fixing issues and developing new features for Foxit Reader for Linux.

So, the crash may well be a consequence of that.
