Hi,
You can easily view the source code of ANY extension on Firefox. They are just simple ZIP files with XPI extension. First, rename the extension from ".xpi" to ".zip" and then extract.

You can read more from here (or just google something like "check firefox extension source code"):
https://superuser.com/questions/771825/how-to-examine-source-code-of-firefox-extension-before-installing-it)

Anything in Open Source doesn't mean that it is safe. Because the one in the repository may NOT be the SAME with the one you INSTALL. This is a simple TRAP that many people will get in.

Hi,
Please clear browser cache and try again on Reddit.com.

Some websites may not work properly with this extension. You can add them to blacklist and use keyboard shortcuts to enable/disable the extension whenever you want.

Hi,
That's a nice suggestion :).
I have added that feature in the latest version (1.6.19+).
You can try it by modifying the value of "Emphasis" options in the extension menu.

Hi,
Some websites are very strictly with their content and will break if we modify them. For example:
- Text nodes being used as placeholders for other elements.
- Add other text node if the original text node changed.
- Running background script to check the text content and will break/cause problem if we change even a single character.

So, I do not recommend everyone to turn on this extension for all websites. In earlier version, I turn off these options on default. However, many people don't know how to enable them and report this extension as "not working".

You can try to combine domains, blacklist and shortcuts for better experience. I have updated the description for shortcuts tab. You can use other characters on your keyboard (not limited to numpads), like: ), (, *, =, _

Hi,
I'm not a professional developer and currently have no public repo at all :)!

Hi,
I have no access to Office 365 webmail, so that I cannot check for the issue. Maybe, the website does not happy to see the text changed :)! Like Protonmail, If we change the text in some special element, it will stop loading.

I have updated the extension to add keyboard shortcuts for some options. You can try these:
- CTRL+ALT+NUM0: Toggle the OFF button. (Use this to quickly turn the extension ON/OFF).
- CTRL+ALT+NUM9: Toggle the ALL button (apply the extension for all websites).
- CTRL+ALT+NUM8: Toggle the DARK button.
- CTRL+ALT+MINUS: Do not allow the extension to run on current website (add to blacklist).
- CTRL+ALT+PLUS: Allow the extension to run on current website (remove from blacklist).

Hi,
Thank for reporting the bug :)! I have added "facebook.com" to the blacklist on default settings in latest version.

After investigating the problem for a while, I have detected that Facebook has a script running on the background and check for content of webpage.

When you click on "See more...", the script will remove "See more..." and add more text. However, because the extension replaces "See more..." with formatted text (something like "See more..."), it is no longer considered as the original element. The script on Facebook will try to remove the formatted text and complain that the text is modified, then trigger an error and remove the post.

Furthermore, I have detected that Facebook has some other scripts running on the background to check for the consistency of the webpage and try to warn user or take action if the webpage is modified too much (in fear of user getting h.a.c.k, may be...).

So, the best solution for this issue is adding Facebook.com to the blacklist, instead of providing a special fix for this case.

As I answered in other comment, this extension is 100% safe. You can easily view the source code by downloading the extension to your PC (XPI file) and then extract like a ZIP file.

About the dark mode, It is not perfect because I'm using a general algorithm for all websites, instead of adding special fix for any particular one. So, you may see some websites with weird background. I just wish we could access the remote CSS file like before, dark mode will be a lot more easier and accurate, no more looping through all HTML elements to background color.

Hi,
In case of ChatGPT, it will keep adding new HTML elements when answering your question. The extension will detect these changes and try to apply styling to newly created text. However, ChatGPT (like some other websites, i.e Reddit.com) is very strictly about the content it generated and will break the page if we modify the text too early.

For any similar websites that have issue, you can add them to the blacklist. Click on the extension icon -> Advanced -> pass the full link to "Blacklist Domains" -> Save/Apply. The extension will trip down the link and will save domain name only.

For more control, you can try "ALL", "THIS SITE" and "OFF" buttons in the extension menu.
- ALL: Use the extension for all websites. Use this together with blacklist for websites that you don't want to use the extension.
- THIS SITE: Use the extension for current website only (active tab). Use this if you only want to run the extension for a few websites that you like.
- OFF: Turn off the extension. For lazy people (like me) who don't want to open Add-ons page and then click on On/Off button.

I have updated the extension to blacklist "chat.openai.com" on default in version 1.6.11.

Hi!
Unfortunately, this extension is for HTML only.
Because the text of a PDF document is rendered on a HTML canvas, we cannot simply restyle it like HTML.
I'm thinking about a solution for now and may add something new to support PDF in the future.

Hi, happy to hear that!

About privacy, this extension collects NOTHING at all.

I defined them as follow in the manifest.json:
"permissions":
[
"storage",
"tabs"
]

1. Storage: To save settings of this extension (this may trigger the permission to access all data. However, only settings of this extension is accessed)

2. Tabs: To reload tabs when settings changes (i.e click on Apply button, check URL to blacklist websites,...).

I just follow the tutorial on Mozilla website.
(https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Implement_a_settings_page)

Furthermore, you can view the source code of this extension to make sure that everything is safe.

1. It's fine for 1 star or whatever. I made this extension to read books and articals on the internet easier. Just want to share with other people who need it, just like me.

2. You can adjust "Skip Text" and "Skip Words" in the options to your liking. Set them to lowest values will apply styling for all text. Please read the "Help" tab for more information.

If you don't mind, please post links to those websites here, so I can make further investigation.

This extension will simply replace a normal text with a block of text. It will not break any web page, unless there are some scripts running on the background to check the content and modify them again. For example, duckduckgo.com will track your mouse movement and keep replacing the text in the search result if you modify them.

3. I added TEXTAREA to the ignore list in the latest version (1.6.1+). Hope this will fix the issue in your case.

- You have to click on "ALL" or "THIS SITE" button (on top of the GUI) to enable bionic reading style. I disabled them on default because I don't like the intrusive way of using a new extension.
- Use "DYNAMIC" button to enable dynamic loading of bionic style. This will reduce memory usage by A LOT on web pages with a huge amount of text. However, you may see the text changing as you scroll down or up too fast.

For more information, please read the "Help" tab.

Update:
- I have released a new version with bug fix for websites that use "contenteditable" attribute in text editor.
- Thanks for reporting this bug. I have never used this extension outside of reading books and articals... my bad :D!

Hi,

I have no issue when browsing Reddit.com with this extension. Thus, I do not know exactly what cause the refreshing in your case.

You can try the following to make sure that there is no conflict with other extensions.
1. Close all tabs.
2. Clear browser's cache completely. (Ctrl+Shift+Delete)
3. Disable other extensions and enable this extension only.
4. Restart your browser and open Reddit again.
