Hi Charlot, unfortunately it's impossible to achieve a restoration rate of 100% on live pages, because Texmarker has to indirectly find the correct text passages after reload. The most common reasons for a failure are the page's content having changed since your last visit or the a script is rendering content after the page has fully loaded. For the latter you can just try the retry button in Textmarker's sidebar.
The only way to assure a reliable restoration of your highlights is to save the corresponding page - i.e. locally or using a service such as Pocket - and combine it with activating saving for immutable pages under Settings > History.

Hello,
Feature requests via e-mail or GitHub only please;) See also the remark on the main page (https://addons.mozilla.org/en-US/firefox/addon/textmarkerpro/) right under "About this extension".

@folder: The history works with tags (instead of folders). You can add tags to each history entry and filter your entries by tag names; this has the same effect as opening a folder - instead of putting your entries in folder "someFolderName" just add the tag "someFolderName" to those entries.

@ref to Wired-Marker:
I'm not sure I understood what you mean. Please follow the feature-request-procedure mentioned above. E-mail is fine, but opening an issue on GitHub lets other users participate as well.

Best wishes, underflyingbirches

Hi Irwan,
a sharing option is on the todo list. Can you open an issue on GitHub or alternatively contact me via e-mail? It would be helpful to discuss with the users what and how exactly they would like to share. Sharing via e-mail would be text-only (no markup), since there is no remote server behind Textmarker.

Hi Larry,
I recommend to test after your first highlights if they got saved.
Saving highlights works for thousands of users. Why it doesn't work for you can have tons of reasons (i.e. wrong OS, wrong usage or simply that you did highlights on a page that constantly changes its content). Therefore I also recommend to read the instructions first and in case of problems ask the developer for help (per email or by opening an issue on GitHub).

EDIT :-) Also keep in mind that Textmarker might not be able to restore your highlights in case the corresponsing page's content changes before your next visit. Address for issues/bugs/feature requests: https://github.com/ufb/Textmarker/issues
