Review summary

Users broadly praise Highlight This as an effective highlighter with clear visual cues, especially for ads. It is described as very useful and sometimes essential. However, recurring issues include backup/restore problems across Firefox and Chrome, cross-browser compatibility, occasional highlighting inconsistencies and color-mapping bugs with regex patterns. Usability and learning-curve concerns also surface, along with a few claims of intrusive behavior. Overall, the highlighting capability is valued, but reliability and cross-browser support need attention.

Pros

Effective highlighter that marks words as users need.
Provides clear visual cues (e.g., highlighting ads and sponsored content) for quick scanning.
Widely regarded as useful and positive by multiple reviewers (e.g., 'perfect', 'very useful', 'so good').
Described by some users as must-have and highly valued for browsing experience.

Cons

Backup/import/export features do not work reliably in Firefox and are not compatible with Chrome backups; cross-browser/version issues.
Highlighting can be inconsistent, missing or mis-marking certain words or patterns.
Color assignment can break with complex regex patterns (Lookahead/Lookbehind).
Not very intuitive; setup and list management can be confusing.
Some users report intrusive ad behavior or ads injected by the extension.

2026-05-27	C*****	This Firefox Add-On does not work at all. I can't create lists (the save button doesn't save the settings), I can't import settings (on the import page the buttons to import don't appear). I've tried a lot of things to get this to work, but it's dysfunctional. I hope the dev comes back and fixes it because it works great on Chrome.

2025-09-04	Cr*****	It struggles to mark stuff. It can mark 032.005 Rx but not 033.124 Temp3Tx. If I just set 033.124 it can mark so I guess blankspace can break it or something.

2025-07-25	Ma*****	Extension no longer functions correctly. Importing a backup is no longer possible. Attempting to import a backup opens a new tab where a file can be selected, but selecting a file does nothing. No data is imported.

2025-07-14	Fr*****	Author, please update the extension! 🙏 Okay, guys, this is a very old version of the extension, it doesn't support backups from a newer one. But there is a way out! I gave the syntax pieces from both versions to the GPT bot and it converted the backup from the new to the old one without any problems.
